Central server for p2p is dying out b/c of law suits, etc. The Gnutella network does not use central servers but the files are what each individual user decides to share. This can make it very interesting because you have users from all over the world. It tends to mean that more than one user will have the same file & thus making it easier to downld. MyNapsters GNetwk ability is probably limited & possibly out of date if it has one.

Try LimeWire instead to see if it suits your needs: http://www.limewire.com/english/content/home.shtml
I imagine it will!
