In fact, we're doing that very successfully here at Waterloo.  We have
a locally-developed LAN (called Watstar), and we use a 386 running NOS
to route packets between Watstar and the Ethernet.

We use packet drivers on both sides.  On the Ethernet side we have a driver
supplied by Gateway Communications for their Ethernet card, on the Watstar
side we have a packet driver we developed locally that encapsulates IP
packets in Watstar packets.

Works like a charm.
