Oh cool. The only reason I chose apt-transport-s3 was that it was included in Ubuntu 16.10. It also only uses stuff from the standard python library so there's less bootstrapping before it is usable.

That does look really cool though. For proxies it would be nice if it supported the standard apt-get proxy declaration. Apt-transport-s3 basically does that and sets the proxy env vars.

You could probably get yours into the offical ubuntu repos if you wanted, though.
