Does anybody know if the msn,aol, icq, irc servers supports JEP 0022??
Since they’‘re not using XMPP, they can’'t use any JEP either.
Jabber Enhancement Proposals (JEPs) are only implemented as part of the XMPP (Jabber) protocol. So, while the protcols of the services you listed might have something similliar to JEP-0022 none of them are going to implement JEP-0022 (or any of the other JEPs) since they’'re not based on XMPP.
Hope that helps,
