I think the biggest problem with Limewire(and other gnutella clinets ofcourse) that it only makes people to dhare more files, not to upload more. I think gnutella needs anti-leech, so the more you upload-> more you download. I can share 1000s of files, but if I set my upload to the minimum, only 1 or 2 files will I only really upload, so I dont need to share the others. Sophisticated anti-leech might be usefull for the global network.
