Just because you have added the new mail check for gmail. I think that
could be also good idea to automatically change the connection server
when server is "gmail.com" or "googlemail.com" to directly
"talk.google.com". To avoid manual changes for this server.
On the other hand I have looked to gajim meta contacts and I see that
you propose you own jabber roaster extensions called gajim:metacontacts.
Maybe could be good idea before release the 0.10 to try to talk with
jabber.org and crate a JEP and permit other programs to benefit of that.
