hi
im working on an graduation project!!!!
i am trying to create a free calling system using mobile phones across a WiFi network. i am trying to implement the system using a hybrid p2p network using c# in .NET framework in visual studio for windows mobile phones.[LIST]
a) I was wondering if this is possible to implement for windows mobile phones?
b) If so, is there any other way to implement p2p connections between two mobile phone without using sockets?

An urgent reply will be greatly appreciated!! Tnx
