Chris,

One problem with assigning numbers or names to micros is that they
don't bind to any telephone or other addresses - since in principle
a micro is mobile. So you need some kind of authentication to assure
that the caller is who he says he is. This isn't insurmountable, but it
is like the X.32 (dial-up X.25 ) problem.
