Dynamic zones: some recommendations?

Hi there,

Well I did have a look at all of this, but it seemed quite stale to  
me since the site hasn't been updated since 2004. If this is not the  
case, and you mention this has been incorporated into 9.4, then this  
is probably the way to go...

Am I right in thinking there's a single configuration entry in order  
that any number of zones be supported? How many others are using this  
in production? What database would people suggest to use as a backend?

Many thanks,
