After finishing a new version of Module::CPANTS::Generater, I actually ran it on all CPAN dists. The result is available as Module-CPANTS-asHash-0.20031208 from CPAN. Additionally, there's a SQLite DB you can get form here: http://domm.zsi.at/download/ or from CPAN:
http://www.cpan.org/authors/id/D/DO/DOMM/cpants_20031208.db.gz
Here are some interesting results / metrics:

(argh, I couldn't get the preformatted text to work without setting everything to 'code')
