I will keep this post short because its late. We have new transports, I have tested only msn and icq which work fine for me. The new transports use a lot less memory and are much faster than the old python transports. This should keep the server as fast as possible for everyone.
 
So right now we support the following transports for jabb3r.net and limun.org:

• XMPP/Jabber
• IRC (this is build into ejabberd anyway)
• ICQ
• MSN
• AIM
• Gadu-Gadu
• QQ
• Simple
• MySpace

Happy jabbering!
