I just dont see the point, why not just leave that as it is and wait for the
XMPP workgroup to sort out proper entries, e.g.

_xmpp-server._tcp
_xmpp-client._tcp

There is absolutely no real need for supporting a newer second record, since
so it worked you would always have to have both entries in the DNS and
always have to do the check you mention, its pointless IMHO since it adds no
value other than simple tidying things up slightly.

My own, I havent released it im letting my friends test it at the moment,
yup its a Windows one and the lookups work fine in 98 SE/NT4/2000/XP, but
not in 98 or 95 yet since I havent found any way in those operating systems
to determine the current DNS server the system is using (when using DHCP).
