I've no experience with SLIP/PPP connections over a null modem serial
cable, but that would be a pretty inexpensive solution. Would he be able
to approach thoese ethernet data rates that way? I'm guessing the answer
is no, but I thought I'd mention it just in case we're overlooking an
obvious solution.
