The more time I spend thinking about P2P architectures, the more I think that IM is the solution. Here is how they stack up:
1) Proven scalability. Compare the ~3 m simultaneous users online at AIM and ICQ with the ~1.5 m Napster and Morpheus (at their peaks).
2) The ability to connect to specific individuals on an IM system vs. the fractional network approach on the current P2P systems.
3) Authorization and buddy lists. IM has it. P2P systems offer the ability to ban only.
4) QoS (Quality of Service) is much higher on IM than the current P2P systems. [P2P]
