Introduction
The P2P protocol is used to exchange data between clients, namely:
- MsnObject transfer:
- display pictures
- custom emoticons
- backgrounds
- winks
- voiceclips
- File transfer
- Games and activities
- Webcam transfer
Overall design
The P2P protocol is layered, it uses:
- a bridge to send the messages (switchboard or direct connection)
- a transport protocol to split messages, send data, and ack arrival (the binary headers)
- a session protocol to invite a client, transfer to a new bridge, or close the P2P application (the MSNSLP data).
More information
For more information, see the following online sources for now:

Note: these sources only describe the flow of the MSNP2P protocol under ideal circumstances, and barely describe the overall picture. KMess is able to cope with a lot more.
