It's brilliant, so long as the complete binaries and source are also
available in case of problems or rebuild or something. There's
something somewhat ironic about how bandwidth requirements are falling
all the time as actual available bandwidth is rising. I note that
apt-get typically downloads diffs to package listings rather than full
listings now. Not a huge different, but it's all gain.
