I am just looking for a little push towards the right direction. I was able to make an audio stream from client to client using WCF in both http and net.tcp however a new question comes up to how would I approach this over a WAN? for an example I have the
application on my computer and my friend in another state has the same application we type addresses in and connect and talk away. Is this possible to do without a server and without configuration (besides typing the other persons IPAddress)? How does AIM
or live messenger approach this? Do they simply use a server as a passthrough using duplex?
