I think its best to leave _jabber._tcp as it is and not add
_jabber-server._tcp because that unneccessaryly complicates things (you
shouldnt change what is already the standard because it complicates things
for all the existing implementations, and all the thousands of installed
servers), but to add the _jabber-client._tcp one in.

My client already supports SRV lookups.
