Dan, I'd still be very interested in your solution. I attempted to make the changes you described, but I wasn't quite able to make it work (I still get errors when attempting to relocate the base and data directories). And I have not yet attempted to figure out how to pass parameters to the MySQL runtime (like a custom "ini" file location). The project I'm currently on could benefit greatly from an embedded MySQL instance inside JBoss, so your timing is impeccable. :-) Any help is greatly appreciated. Thanks.
