Good-o. There's actually another problem with cross-deb pieces, which is
that if one of the packages you didn't download entirely gets updated,
you can't share the package you did download because you'd need to be
sharing a piece that's half the updated package and half the package your
using, and while you have the latter, you've only got the old version
of the former.

Yep. Not as many slots as we'd hoped, so even more reason to get all
the projects we got this year to kick butt :)

Yup. Feel free to forward these mails somewhere public once you've found
somewhere, just for historical record.

How about "apt-tornado" given we're presumably going with the bittornado
codebase, and trying to make it usable by apt?

debtorrent sounds fine to me too; btmirror was a good name but this is
really a different implementation, so it's not completely sensible to
reuse it.
