Sorry but I doubt Limewire would move away from the Gnutella network, if they used anything else, the RIAA/MPAA would surely close them down in a heartbeat. If a P2P doesnt use gnutella, the most widely used, they it will be too limited. and, I dont think LW would want to limit file sharing, they wouldnt be able to make money off their Pro version if they did that.
