a few questions on tcp/ip:

1)  For macs on a localtalk, there are only two possibilities for accessing
an IP network:

  a)  A router that will take IP packerts from another network
  (like an ethernet) and ship them over to the localtalk in IP
  format.  Does this include the fastpath?  Ethergate?  GatorBox?
  MultiGate?  Ungermann-Bass?  Anyone else?

  b) A bridge that will encapsulate IP packets into AppleTalk packets
  and ship them over to the Localtalk network.

Is this right?  What are the advantages/disadvantages of each
of these methods?  I believe that pure IP formatted packets
wouldn't get across any appletalk routers in the localtalk since
it's only looking for appletalk packets, correct?  Also,
Encapsulated IP packets, though they would solve the appletalk
router problem, would need to be treated differently at the Macs
since telnet software is looking for IP packets, not
encapsulated packets.  is this right?  Does anyone know what
software will do this?  Is it just a special driver at the Mac, or
does it require completely different telnet software? Is this MacTCP?

2)  A completly unreleated question to the above:  Can AUX broadcast
IP packets out it's localtalk port, or only through a real network card?
If it does, are they pure IP or are they encapsulated?  A friend of mine
just got AUX up and I was wanted to login to it from my Mac over localtalk
using telnet.  Is this possible with only localtalk?
