[Serusers] On the diversity of instant message protocols

[kaiduan xie]

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.
