Hi, all, Now there are so many different instant message services and clients, for instance, AOL, MSN, YAHOO messager, and so on. I have a question on the diversity of these clients and the protocols behind. As we know, SIP has gain more and more momentuams. Will SIP replace all the other instant message protocols? If yes, how long will this process take? Besides, can anyone tell me where can I find the protocol used in MSN messager (not Windows messager), YAHOO messager and AOL messager, repectively? Thanks a lot for help. kaiduan ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca _______________________________________________ Serusers mailing list serusers(a)lists.iptel.org http://lists.iptel.org/mailman/listinfo/serusers
