Another quite simple solution would be to get two new FTDI USB-Serial
chips (FT8U232AM) and cross their serial in/out channels. Then you get
two standard serial channels and can run whatever you like (PPP) over them.
The required hardware is just one chip, one crystal and maybe 10 passive
components. A student can assemble two boards in half a day easily.
FTDI supports up to 2 Mbps serial links so it should be somewhat fast.
