Yes, it's a common topic on this list. :/

Yes, they do.  The Google Talk team wrote their own implementation of XMPP
(including dialback), whereas the jabber.org service deploys the ejabberd
codebase. However, I think that jabberd14 was updated to enable
communication with Google Talk's implementation (which takes advantage of
some behaviors that are not exactly forbidden by RFC 3920, but by the same
token are not spelled out or recommended).

That said, if you can share presence then you should be able to exchange
messages. I doubt this is a dialback issue -- it is more likely related to
rosters (i.e., perhaps the subscription states are out of sync, i.e. your
server thinks you have a bidirectional presence subscription with the Google
Talk user but Google Talk disagrees -- try re-requesting authorization).
However just to be sure you might consider deploying the proper DNS SRV
records for your domain, i.e.:

_xmpp-server._tcp       IN SRV  30 30 5269 darkcoding.net
