I had a look at it and can tell that it is a different approach. I'd
like to have simple nix expressions for every package so people can
customize them if needed and the nix-expression-generator can then be
taught to incorporate those customizations.

It would be great to have your know-how about that! Would you be
interested to help with another approach and join us for at least a
couple of days?

http://wiki.python.org/moin/PyPiXmlRpc claims that this is available via
pypi, but I have not tried to query that info yet.

However, I see a whitelist of packages we want to package, we download
them, checksum, generate EGG_INFO and create an expression for each
package version we want to include.

What is needed for maintenance with your approach?

Will do!
