Not sure how software package management and updates will be done.
I personally prefer (and it was policy so far) to use Debian packages,
in order to get Debian upgrades. That would rule out using Postgres 9
at this point.

Also, I'm skeptical that Posgres replication could actually improve 
availability. When PyPI becomes unavailable, it is typically not
because of Postgres, and I would expect that the added complexity
of supporting failover would actually reduce availability, and
introduce the risk of data loss.

I think that, for the rsync backup, it's only tummy.com. Of course,
there are tons of PyPI mirrors, but they are not using rsync, and
not doing backup.

Thomas set this up. I believe the motivation is that only this
setup will support multiple vhosts. It actually supports auto-
detection of vhosts, where new log files will trigger the creation
of new webalyzer configs.

No.

I think it got installed as a side effect of installing something
else that had printing as a Debian dependency.

I'd still urge that IPv6 connectivity is made a pre-requisite for
switching providers.
