To speed up deployments, we use pip's --download-cache option, so all 
builds on the box share the downloaded tarballs.

We also use our own local mirror, and an extra apache directory for 
packages that are not on pypi.

I have also added a proxy that returns a 404 when pip tries to hit the 
net, to simulate the --allow-hosts option easy_install has.

Everything is driven from a Makefile. Example: 
https://github.com/mozilla-services/tokenserver/blob/master/Makefile
The script to create RPMs is at 
https://github.com/mozilla-services/mopytools
