Hmm.  No, I don't think so.  There's no "quantizing" of lightspeed that
I
know of, though you may be remembering the argument that it's only
technically impossible for a massive particle to travel -at- lightspeed,
but tachyons would be able (and required) to exceed it.  See my previous
message about that, but I bet that's what you're thinking of.

Unless you're referring to some thoughts towards a theory of quantum
gravity, which some people in my group are working on, but no one in the
world is really even close to.	I'm afraid I'm out of my depth, beyond
the
very basics, with that subject though...
