We actually made excellent progress at this during the last sprint (how many months ago was that?!). It is very difficult because IMO, an object database is a better fit for Mailman's data model than a table. Tools like SQLObject (which we used during the sprint) did help out a lot, but some of the access patterns resulting in fairly convoluted queries. -Barry
