Wii-Chat is a peer to peer android chat service built by myself and Shubham Atlani under BITS Pilani Android Research group.
Using Wii-Chat one can communicate with another in a Wii-Fii. Currently by using the existing version one can only chat. Development is going on to extend the existing framework to include VoIP. This later will be merged with the internal VoIP phones enabling phone call from anywhere to anyone within the University premises. Hence direct call’s within the campus will be free. The only question is will the bandwidth be in a position to handle the data flow. But again like I said this is a research project and they are meant to be ambitious 😛

The Chat version is built and hence the framework to merge phone call’s is complete. Stay in tune here for more information.
