First, when you start a new thread, it would be great if you could start a thread :) Please don't reply to an old message and simply change the subject line. Threaded mail clients will put your message smack dab in the middle of some other thread.

Secure, robust and ideally suited to certain tasks. I'm not yet convinced this is one of those tasks. I assure you, we're not dismissing the idea out of hand. We all had serious conversations (in person, so no links to point you to) about this a while back. > Instead of directly integrating BT into YUM, I'd propose creating a BT > client/server that acts like FTP.

Let me see if I understand you. You're suggesting some intermediate protocol? Some FTPOBT (FTP over BitTorrent) that would look and feel like FTP at both ends, have some translation layer, and do bittorrent underneath? FTP and BT are VERY different protocols and in practice it's difficult to make one protocol look like another. > I'm thinking that we could create scripts for mirroring popular RPM > sites by having a low-bandwidth server that downloads them periodically, > and making them available as torrents.

I don't understand what you mean by "FTP-like utility" well enough to comment on that. > So, in summary, I suspect all we really need to integrate BT and YUM is > build an FTP-like utility based on BT for pubishing file systems and > downloading individual files from those file systems. > > Should I work on such a beast? If you want to pursue this, I'd encourage you to look into how yum/urlgrabber currently do the network stuff. For example, yum currently relies heavily on the ability to extract JUST THE HEADERS from an rpm on the server. FTP/HTTP/File can do that, but BitTorrent cannot. -Michael -- Michael D.
