One important thing to know is that "port.p2pj" is deprecated and is
no longer being used. You should not depend on this key being there
in future versions. The way you determine the port number is by using
the SRV record, not the TXT record. So use the standard Resolve API
to discover the port to connect to.
Also, "version" is deprecated as well and it will be disappearing in
future versions. The replacement key for "version" is "txtvers" which
is the standard DNS-SD method for versioning the TXT record keys.
Currently it will always be 1, but you should add a check in your code
to require that "txtvers=1".
What Marc said. "port.p2pj" and "version" are only put there for
compatibility with the iChat AV public beta, which has now expired, so
you can bet that future iChats won't have them.
Also, note that the DNS-SD specs say that the "txtvers" property MUST
come first in the list.
