Comment (by The_Fac):

 Found this interesting information on Wikipedia that may help those that
 are inclined to work on this.

 http://en.wikipedia.org/wiki/Windows_Live_Messenger#Final_Version_of_8.1

 Protocol

 Windows Live Messenger uses the Microsoft Notification Protocol (MSNP)
 over TCP (and optionally over HTTP to deal with proxies) to connect to the
 .NET Messenger Service—a service offered on port 1863 of
 messenger.hotmail.com. Its current version is 15 (MSNP15), used by Windows
 Live Messenger and other third-party clients. MSNP15 introduces a
 different authentication mechanism. The protocol is not completely secret;
 '''Microsoft disclosed version 2 (MSNP2) to developers in 1999 in an
 Internet Draft, but never released versions 8, 9, 10, 11, 12, 13, or 14 to
 the public. .NET Messenger Service servers currently only accept protocol
 versions from 8 and on, so the syntax of new commands from versions 8
 through 14 is only known by using sniffers like Wireshark.'''
