As per my last post, there is a new namespace (System.Net.PeerToPeer) available in the .NET Framework "Orcas" March CTP tailored to making it simple to write P2P applications using managed code.  I have posted a write up (with code samples) on the P2P team blog which digs into Peer Name Resolution Protocol (PNRP); one of the many technologies in the new namespace.  PNRP is a cool new technology which provides a serverless name resolution solution tailored to P2P scenarios.  Check it out and let us know what you think of the new features in System.Net......
