Your scenario is superbly thought out, Peter. It reveals a mind far above average! However, even people who are on much the same wavelength will disagree about details on occasion. That makes for good, intelligent discussion - which is one of FQXI's goals.
I think your video's explanation of quantum mechanics is a bit too complicated (at least for me). It's simpler for me to imagine QM resulting from a universe-spanning gravitational field whose waves can travel back and forth in time, cancelling to produce lack of distance in space-time known as entanglement. Ptolemy's epicycles succeed in providing explanations and would probably make sense to a barmaid. But astronomy has, with time, come up with better models. Time obviously does exist and I don't think Feynman's, and TIQM's, 'wave going backwards in time' stands out like a sore thumb. This "reverse time" can be explained by the Complex Number Plane being given physical, rather than purely mathematical, meaning (since I'm an incredibly slow typist, I'll copy and paste from things I've already written - so forgive me for overexplaining topics).
The Complex Number Plane has a leftward direction from 0 on the horizontal X axis which is called the "complex axis" and corresponds to backwards motion in time^. The direction to the right of 0 on X is called the "real axis" and corresponds to forward motion in time, while the vertical Y axis intersecting the X axis at 0 represents the so-called Imaginary Time derived from Special Relativity and quantum mechanics.
When Max Planck originated the idea of quanta to solve the ultraviolet catastrophe, I'm sure that idea (like so-called "imaginary" time) was initially thought of as a mathematical trick. Albert Einstein thought differently about quanta, and developed his photoelectric effect. So it appears entirely possible that imaginary time and the Complex Number Plane will find practical application in the future.
^ The photons in a beam of light - or the theoretical gravitons in a gravitational wave - going back in time could be the hypothetical particles called tachyons. Experiments have been conducted to search for tachyons, with no compelling evidence for their existence. If such particles exist, they always move faster than light. Special relativity says this means they travel back in time and cause violations of causality, the relationship between causes and effects. I don't think it violates causality since the tachyon would be the cause and it couldn't affect a particle until it began its journey back through time. What it does violate is the idea that time only ever moves in the forward direction.
Time's obvious existence - together with the tremendous appeal your video has to me - cause me to prefer explaining quantum mechanical things like entanglement as "a universe-spanning gravitational field whose waves can travel back and forth in time, cancelling to produce lack of distance in space-time". To address another example (quantum tunnelling) - Inside black holes, their gravitational and electromagnetic waves possess both forward and backward motion in time, cancelling to produce the zero time/zero distance called entanglement (this allows instant travel to the past, the future, and other planets/stars/galaxies). Physicists now believe that entanglement between particles exists everywhere and that moments of time can become entangled too - "The Weirdest Link" (New Scientist, vol. 181, issue 2440 - 27 March 2004, page 32 - http://www.biophysica.com/QUANTUM.HTM and "Quantum Entanglement in Time" - http://www.arxiv.org/abs/quant-ph/0402127). If there's zero time and zero distance between the inside of a black hole and the seemingly empty space surrounding it, the gravitons and photons of the black hole can exist outside a black hole's boundary or event horizon as "pairs of particles of light and gravity ... (with) one member of the pair being a particle and the other an antiparticle (the antiparticles of light and gravity are the same as the particles)" - "A Brief History of Time" by Stephen Hawking: Bantam Press, 1988, p.106. In other words, the particles "quantum tunnel" and cause Hawking radiation.
About 55 seconds into your Classic QM video, you say "Spin, in QM, can't be rotation". I also prefer to explain spin not as rotation on an axis. However, spin on multiple axes doesn't satisfy me and I use the gravitation spanning space-time. According to General Relativity, matter causes a gravity field by its mass creating depressions in space that can be pictured as a flexible rubber sheet. Space could affect particles through its curvature (gravity) infiltrating particles, thus giving them quantum spin. The curvature of my essay's Mobius strips implies this quantum spin could be continuous. Since it's known this type of spin can only have discrete values, these values (and space's curves) must be determined by individual pulses of energy (fluctuations / pulsing of virtual particles* could produce the distinct values of binary digits' on-off states, or 1's and 0's). Space's curves influencing particles is consistent with Einstein's 1919 paper "Do gravitational fields play an essential role in the structure of elementary particles?"
*The motions of virtual particles filling space-time appear to be random but a principle of Chaos theory - perhaps science's most important theory after relativity and QM - is "order within apparent disorder". So their randomness may well be an illusion.
Bell's theorem says any system of Hidden Variables that agrees with QM's predictions must be non-local. The binary digits (bits) I speak of are hidden variables, removing probability and restoring exactness (a precision hidden within apparent disorder). The digits are the most basic composition of gravitational waves, and the universal nature of these waves and bits, plus their trips back and forth in space and time, causes them to immediately affect any distant location ie be non-local.
