I still dispute your opinion on this, a client having to act as a server can
create more problems than it solves IMO (as already discussed), and IMO its
not really any easier to participate in.

Have you changed your mind on the complexity? you say at the top of this
email that its no complexor to implement p2p than it is client server, seems
a bit of a contradiction.

Its just as bad for the client acting as the server (in bandwidth terms) as
it is to go p2p, also I would disbute that it would be 10 times as much
bandwidth for the rest, adding silence detection (which you seem to have
oddly put aside and ignored) reduces the p2p bandwidth use massively, also
as I have shown previously the mixing requirements are less on p2p clients
than on the "server client". Also having a server client creates a single
point of failure which you also seem to have completely put aside, there is
also the latency issue that you have yet to address and until you do address
this satisfactorly I will not be convinced by your strange need to make this
client server mode only, for which you still havent provided sufficent
