Enginerd: Am a bit confused about the second one...
ie, what are the consequences of the fact that the phase of the wavefunction as a whole is irrelevant, that is, that one can arbirarily rotate the whole thing without changing anything. The fact that switching two photons is a meaningless physical op affects the structure of the configuration space, thus what can interfere with what. I'm not sure what actual consequences we can see out of the fact that we can arbitrarily rotate the whole thing in the complex plane without affecting the physics at all.
