I love BitTorrent. Not because it lets me steal the w4rz0rz, but because it's a really great new transport for large downloads. I've been impressed with Bram's stewardship of the protocol and am glad to see he's pursuing commercial options.
But open source protocols in hackerland are fragile, there's a danger they fragment. And that seems to be happening with BitTorrent. I'm seeing torrents now with three kinds of tracking: the standard TCP tracker, UDP tracking, and trackerless. Which client works for all?
I'd been wondering why my torrent downloads recently weren't working. I think the problem is that Debian testing installs bittorrent 3.4.2-4, which doesn't seem to work very well. The 4.0 .deb from bittorrent.com works better.
