with "other" Linux programs as well such as Xastir:  Yes.  Xastir
(perhaps multiple copies) plus many other programs can share a TNC
or multiple TNC's this way.

There are distributions that contain working AX.25.  SuSE (certain
versions) does.  I believe Debian does as well.

Yes.  You could either attach it to a local aprsd port or to a local
Xastir server port.  I've done so, but not for messaging.  I either
inject packets into the APRS-IS (or Firenet) or scan the APRS-IS
looking for certain types of packets, using Perl.  Works great.
