I think you're in for a considerable amount of work.  If you're up
to it I applaud you :-)

Besides adding the handling for gateways, routing and possibly even
packet forwarding, you'll need to add IP fragmentation and better
TCP window support.  The [very simple] stack in RedBoot has none
of these.

You might get away with a slimmed down package if you know that there
is always a router/gateway nearby and you convince it to not hand
you anything ugly.

As I said, "tons of fun" :-)
