Use Linux to share and rotate the files day to day via a perl script so no one file is up for more than 24 hrs. Then leave your client on all the time and share about 2000 files at a time so you don't bog down your computer, and so you don't get busted by your spy-on-you ISP.
No need to create a file list, gnutella clients will do that for you, and people will find your files with no problems.
Thanks for sharing!
