We have some Macs with Ethernet cards, and on the same ethernet sit a
variety of Unix machines. I hoped to run Columbia's CAP appleshare server
on one of the unix machines, and access it from the macs directly over
the ethernet. However, unix needs TCP/IP packets, and ethertalk packets
aren't TCP/IP. If we were running our macs on a localtalk network and using
a Fastpath to connect to the ethernet, then the Fastpath would encapsulate
appletalk packets in TCP/IP and everything would be hunky-dory. But we aren't.

Is there any software that will perform the encapsulation directly on
Macs? Or if we have a Fastpath (or GatorBox) sitting on the ethernet,
would it notice the ethertalk packets wizzing by and encapsulate those
so the unix machine can understand them? I can hardly believe that we
are out of luck and have to hook up through a Fastpath or Gatorbox.
