That seems awfully optimistic.  How are the people supposed to find each other?

Also, in the absence of a central server every participant needs to
send N streams to the N other participants which is going to be a
challenge on the cable and DSL connections most people have that have
limited upstream bandwidth.  With a central server, even if it can't
decode the streams,it can switch and multiplex them so each client has
one stream to the central server and one multiplexed one back.
