Except, mysql really isn't the lowest common denominator.  They have a spate of 
non-standard SQL extensions that are widely and popularly used -- mostly due to 
history.

It'd be nice to get folks to use more standard, portable SQL so that we could 
support more db types reliably.  What's the method to get there?  Unit tests? 
Dev documentation?  An SQL audit before CVS commit?
