On a somewhat off-topic point, the photino, which is the proposed superpartner of the photon, will not be massless. If it exists, we know for sure that it will have a mass significantly larger than that of the electron. For starters, we would have already discovered it if it had such a low mass. Therefore, it is incorrect from a particle physics perspective to consider the photino lighter than an electron.

And yes, I know this is why people don't like talking to physicists. Good luck with the project anyway :)
