I've started playing with the Chat sample for WCF P2P. I've modified the sample to use the PNRP binding instead of the custom resolver since I want a pure p2p network with no designated servers (or am I not understanding something here? Am I supposed to run the custom resolver service on each node?). Each chat instance now takes approx 20 seconds to join the mesh using PNRP. Presumably that's the time it takes for the PNRP server at microsoft to get back with an answer? How can I limit the scope of my PNRP binding to just the local subnet?
thanks.
