Fingerprinting

The idea is to make a plugin to get the exact client information, because not every client sends x-clientcaps.

Techniques to fingerprint clients:

• Alteration of p2p packets
• Direct connect availability
• Keep-alive behavior (kopete, for example, sends keepalive in every sb connection)
• Client id (capabilities)
• Msnobj parameters order (some versions of wlm send Location="0" in CE msnobjs)

Please add every variable you think that could vary between clients.
