this is my 1st post, so: greetings everybody! ;-)

I'm looking for a sample WCF application (as a base for something more sophisticated) which will listen on a given port and when it gest any data it'll pass it to and IP given earlier (and there will be an another instance of this software, also listening)
This is supposed to form a ring

I'm also new to C# WCF programming, so can You help me?
