I would like to create a small "Windows Messenger" Client that I can trigger from a script (essentially a notification Bot). It's internal, so I think it uses SIP or SIMPLE against a Live Communications Server 2005.
Now, before I dig through the RFC's and Wireshark logs, I wonder if there is a .net Library already available that does this? This is for a Server-Side Application, which means that it should work without a GUI and that it should not use unmanaged code.
dotMSN does not seem to support SIP, and SIP Objects.NET seems to be aimed only at telephony rather than IM.
