A patent on p2p- US Patent #5461624 - distributed routing
I ran across several patents on P2P, specifically in P2P content delivery.
Allcast has US Patent #5884031 - “Distributed Routing”. Here is their tech page: Allcast - Our technology
Chaincast seems to have US Patent #6249810 - “Method and system for implementing an internet radio device for receiving and/or transmitting media information”. Here is their tech page: Chaincast Networks
I wonder how much this affects the competive space and if it has any broader ramifications for restricting P2P applications.
