No, it doesn't. It stores IPs as text, and does all the conversions
of it in python.

Fedora uses a MM script to dump the database once an hour into the
mirrorlist cache, then rsync's it to the target mirrorlist servers.
kill -HUP mirrorlist_server.py and it reloads the cache.

Uh, no... I can dump the schema as SQL, if you know of a tool to pull
it in. I can help with the script too.
has the schema in SQLObject. Each class (SQLObject) is a table.
