btw--I know what you mean about those rare sources. You can probably do a better job than the code, though, at guessing when those sources are online. I've waited weeks for some who usually show on a Friday evening or recently, midweek. Check out http://www.limewire.com/english/content/netsize.shtml to see the daily/weekly fluctuations.

cheers--I'll look forward to when the code gets good enough that there are so many users we can leave our machines running 24/7
