how to add RDV and relay peer in new group
I try to describe my application clearly.
1) I have a server ( we can name it "S") located in US which can run as relay and RDV point for all peers (groups)
2)many peers joined an open group
3)if two peers( maybe in different LAN) want to transmit some private data, one of them can build a private group. then login name and password are sent to corresponding peer through a pipe
my questions are:
1) i know every group should has its own RDV, is it means "s" should join every private group? can anyone of these two peer work as RDV?
2)does every group need a relay peer?
3) all RDV and relay seeds are added before startnetwork, how can i add RDV or relay when a new peer is built?
