When I download new versions of linux via bittorrent, I get a steady 300KB/s its great, those 3+ CD's download in no time.
I have even used it to download games that I already own but have bad CDs (I have some that have "top" scratches...I have a 5 year old boy, what do you expect!)
I could give you a link to a bittorrent site (the most popular bittorrent site) with thousands of working links/torrents that has many many mirrors and has been up since bittorrent day 1, no viruses etc... But they have "Cracked" and "Pirated" games and software mixed in with their free (linux, demos, etc..) torrents so its not something that this forum would like to have posted.
If you are interested in linux isos, free games, demos, etc..., (no warez people please), PM me and I will give you the URL if you dont already have it.
