[Chameleon] What does chameleon do?

[Paul Spencer]

Hi,

don't have time to respond properly for a few days given the holidays, 
but I don't think the SQLQuery widget will do what you want, but it 
should be possible to do it with mapserver and ogr using virtual 
datasources ... will discuss when I have time.

Cheers,

Paul
