Limewire Code
 

Xolox would be such a better program if It implemented some things from limewire's source like message compression. I'm not sure exactely what it is but something else im limewire creates better scalibility for the network.(not trying to spam or advertise..im serious about implementing these things)

If I'm not completely mistaken, XoloX is not written in Java so just copying the code will not work.

Anyway it's always a good idea to keep up with the latest innovations, - and in the case of dynamic querying LimeWire was the first to implemented and achieved fantastic results.
