- Quite true; I should have said something about "controllables" or
- something like that (language analogous to that in one of Bell's
- essays, in his book). There are many subtleties in this business,
- like the Herbert photon-cloning which turned out to be incompatible
- with the linearity of QM. I guess the problem is that there are so
- many proofs that FTL communication is impossible, that I am more
- interested in the thought processes of the people that propose FTL
- communicators than in their actual devices. Closed-minded, ain't I?
