MySQL itself has at least four different backends - sufficient reason to 
avoid it in my opinion. Things have improved sine MySQL incorporated the 
SAP-DB (now known as MAX DB, I think). In your case you will need to check 
which one provides the best support for your GeoData.

Zope certainly is an excellent platform for integrating RDBMS quickly and

Who needs version numbers? Works fine for

You have to work your way through it and ask on the mailing list. The best 
thing is to try a few of different types of membership and property source. 
You may well find that XUF already has a scheme pretty close to what you 
need. Other than that - hat off the Andrew Milton who wrote and maintains it 
and is always very helpful on the mailing list.
