I don't know how you would get to it without hacking hardware and putting
an Ethernet controller in external address space, and then writing the
code for it. One problem: Ethernet needs a far amount of buffer space to
keep up with packets and that is one thing you have little of.

Well, I plan on building networking code, but it won't be full IP. However,
it would be easy to have an IP proxy running on the host computer and
relaying packets over the IR.
