Dear Tejinder,
thanks for reading my essay, and for your kind comment! Your paper looks fascinating, I will have to carve out some time to delve deeper into it. A 'geometrization' of quantum theory (albeit with some algebraic input, it seems) would certainly have been something of great interest to Einstein!
I wonder if you've seen the recent proposal deriving quantum mechanics from special relativity due to Dragan and Ekert: essentially, they take the (usually discarded) superluminal solutions to the defining equations of the Lorentz transformation, and show that keeping them leads to very quantum-like behavior.
I sometimes wonder: with such proposals to get the quantum from relativity, coupled with the proposals to get relativity from the quantum (as in the recent spacetime-from-entanglement program), perhaps we've been talking about the same thing all along! Maybe, in their own sense, both Bohr and Einstein had it right---after all, as the former is supposed to have said, the opposite of a deep truth may also be a deep truth.
Cheers
Jochen
