[c-nsp] Appletalk (don't laugh) through Cisco switch

[Ted Mittelstaedt]

In Apple parlance they called that a "seed" router, and you don't
need to use a router, you can use a Netware server running Appleyack,
or a UNIX box running netatalk.

I think the 128 limit is Appleyack Phase 1, I think Phase 2 solved
that.
