I have a version of the mysql package that works with 3.7 (37b5). I made the 
changes for the new network code. I had thought that the mysql driver on 
Squeakmap was up to date but if not, I'd be happy to put up what I have.

I've written an object persistence layer that works with mysql. It could some 
further  development but it's solid, I am using it at www.e4ward.com. I was 
thinking of contributing it if there's any interest.
