MsgPlus! will
never have a P2P in it. (Patchou has said so himself).
And I doubt MSN would make such thing too (a
real P2P, I mean), since a few days ago they made a new law that allows to sue companies that "help" the Internet piracy.
Edit: btw, this is the wrong subforum (Forum & Website). You should have posted in "MSN/Windows Messenger".
