Isn't it true that 50 ohm transmission line drivers and receivers can be
reliably and economically made in CMOS? I have seen quite a few papers
in the IEEE Journal of Solid State Circuits outlining how to do just
that. Once you have a controlled impedence transmission line on your PC
board, _any_ data rate is possible provided the internal data rates of
your chips are fast enough, and your line drivers and receivers are up
to it.
