so, Oct 2000... That is a little out of date, ain't it? That were still the days of gnute.com. I had already tried gnutella that time and it certainly has change since.

I analyzed a gnut host list, which was three months or so old and out of 10k hosts there weren't any more than 3.5k hosts not sharing any files. Note that this is not accurate at all, since freeloaders have a much shorter uptime on Gnutella they appear and disappear at a high frequency, while the clients sharing lots of files usually are online much longer. So those numbers don't mean there are 35% freeloaders at any given time, but 35% of the hosts seen in about 20 hours were freeloaders.

About Fasttrack... I know about Fasttrack, because I'm a freeloader on the Fasttrack network (usually 1GB per day). Miao yourself!
