  There are software modems out there.  There are companies dedicated to it.  I
don't know of a copylefted version.  They require something on the order of
a pentium 120 to kick out 14.4 I believe.  There are WinCE (Phillips I think)
machines that have SW modems...they seem to degrade power by about 80% so
your 20 hours turns into 4....but still quite a bit better then the 30 minutes
someone said they were getting out of PCMCIA devices.
  Interesting enough, I don't believe it is the transciever or D/A that get
you, it is the all out nature of the code that is required to run.  Most
of the low power machines get 20 hours by psuedo dynamicaly clocking the
machine at 'adequate' speeds to save on power.  Software modems stress most of
these systems so much they run all out....at a much higher power consumption
rate.

Most of the WinCE machines are on the order of Pentium 90-120 type performance.
