The "KIP and CAP setup" (also called IPTalk in some places) consists of
two separable parts. One is indeed "Phase 2 Compatible" and the other isn't.

Mac HOSTS on LocalTalk didn't notice any change with Phase 2. This is because
LocalTalk is designated as a "Non-Extended" Network. None of the Zone and
Network extensions apply. IPTalk (as practiced between routers and hosts)
is also a Non-Extended Network. No change needed for Phase 2. There may be
a small requirement for ATIS to now check the Zone name before answering
NBP LookUps, but that's someone else's field. Talking to CAP hosts
should still work on AppleTalk Phase 2 internets.

ROUTERS on LocalTalk (all networks, not just extended ones) did have to 
change in order to be able to handle the new routing information. Thus the
ROUTING part of IPTalk (that part that gets you from one AppleTalk network
to another via IP) won't work with an AppleTalk Phase 2 network which is
using the extensions. It should still work if the AppleTalk network is
still in "Phase 1 Compatability" mode - which you have to do if running
both Phase 1 and 2 together anyway.

CAP doesn't care. The router-related stuff does. There are proposals afloat.

Probably running native EtherTalk rather than IPTalk maybe (for A/UX)?
