[muscle] Re: peer-to-peer help intro

Thanks for the fast reply Jeremy!  

I am writing in C++ and though I learned it in
university, it's been quite a number of years since
I've touched it.  I'm writing for Win32, and for my
first project I want to do a simple chat app
(peer-to-peer) where the IP addresses of both chat
clients are already known.

So I looked at BeShareAndMuscle.html and based on
that, viewed class Win32MessageTransceiverThread from
the API.  It seems method AddNewConnectSession() will
connect to the IP and port of the other MUSCLE client
I want to do peer-to-peer with, then I can get any
messages by looping for events through
GetNextEventFromInternalThread().  The event code will
tell me whether I have a Message object.  For sending
messages, plainTextClient.cpp shows a method
"sendOutgoingMessage()" of MessageTransceiverThread
but I can't find that in the API.  What do I do to
send a message?

For what I want to do, I can't believe it's this easy.

One fundamental question I have is, is the same code
used for peer-to-peer as for client-server using
muscled?  That is, instead of connecting directly to
your client in peer-to-peer, connect instead to the
server, pattern-match nodes for who to send to, but
then get or send messages in the same way.  Is that
right?

What about client-server with subscriptions?  The
Beginner's guide mentions how to set one up, but
doesn't mention how to subscribe.

Are there some full samples of peer-to-peer and
client-server that I can study?  I couldn't find any.

I hope my questions aren't too ignorant... but I do
appreciate the help.
