What would be nice to have is a 'virtual' query that would render
a 'virtual' data set.

We have the GDAL ".vrt" data mechanism what is missing is the
equivalant 'query' mechanism to create these dynamically from
something only the developer of the site knows about.

Of course there is always mapscript which allows you to do
this and *much* more :-)
