[Mapserver-users] application opinions

I haven't done it, but this sounds like a good case to use a table 
join. If you create a unique dbf with a key and the 4 fields you want 
to change, then you should be able to join that with the standard 
shape/dbf pair and use the added fields as attributes. Each user 
could have it's unique dbf.

I will defer to other on how to actually implement this :)
