Well, you could use PPP, which would then be easy to interface to a PC
host...  BUT then you're limited to a point to point connection.

Well, the Siteplayer folks sell an Ethernet jack with the inductors and
stuff built in, so just an Ethernet chip like a CS8900 or Realtek...  but
those seem to have some pretty hefty I/O requirements, IIRC.  On the other
hand, they do have packet buffers so you can wait until they have a
packet, then peek at it without having to burn a lot of RAM.
