Another option which just arrived is the Telebit modem, being marketed
by Digital Communications Associates (PC Irma coax interface board et 
al).  This is a proprietary asynch scheme for 9600 b/s which purportedly 
can adapt to changing line conditions on the fly in increments of <100 b/s.
They do this by subdividing the bandwidth into numerous subchannels
to spread out the information.  I seem to recall price for the
stand-alone unit to be about $2400.  I mention this since, as they
are currently selling for the volume PC marketplace, they are likely
to become a de facto standard.  I believe the information number is
1(800) TELEBIT.
