Generic features in iPhone peer to peer App, ideas needed

My student project is to develop a Generic Framework for peer-to-peer system on handhold devices.(iPod)

There is already an existing framework(Gamekit) that build the network and send messages, I'm working on top of it and trying to develop some 开发者_Python百科generic features for common p2p applications.

Any idea what function would be Generic here?

You will need some minimum functionalities such as:

• linking a given device with an IP address
• finding the ip adress of a given device on the net
• Eventually techniques to perform NAT traversal
• establish a couple of central peers to bootstrap your network
• request/echange electronic resources between remote devices

Of course, you will need to design some standard messages between peers to perform those transactions
