Isn't that kind of starting in the wrong end? And it's one of the more
complicated things to write -- at least if you want to do it "right".
It's also the most memory hungry. Before you can write any internet
app at all, you need to have TCP/IP running, on top of PPP or Ethernet
or whatever.

You'll have to work around the PLA though. Writes to the $8000-9fff
area are directed to the underlying RAM.
