Gnutella Forums - Simulation

I simulated a simple learning-based resource discovery method, now I want to implement it on a P2P file sharing networks, i.e., replaced this learning-based method with existing one, in order to achieve real implementation not simulation, but in most of research articles in this scope, methods have been simulated (due to large scale and bootstrapping problems).
Could I implement it using JXTA for unstructured P2P systems? Is it possible?
I need it for university project, but I have not been assured that in P2P area real implementation is feasible.

thanks in advance.
