MSN protocol resources

if you want to learn how the msn protocol works, here I give you some links to read :)

• Hypothetic: pretty outdated but useful to start..
• MsnPiki: a wiki with updated content
• MsnFanatic forum: a forum you know :P, you can find interesting threads there
• Siebe documentation: great resource for p2p, I don't know why he removed it (using internet archive)
• imfreedom: new but pretty empty
• some useful msn msdn links :D

The tools I use to debug and find new features are wireshark and ospy, both great tools, ospy is easier to use, but you need windows and WLM

Orfeo C recommended SocketSniff, I did't tested it, but it may be useful for someone
