Partially I can use it to map usertypes. But the biggest challenge is 
the fact that the layer is created by dynamically selecting objects from 
a postGIS database. So the DATA parameter in the Mapfile is dynamic:
DATA 'the_geom from select * from sketch_points where pointsetID = %X% 
as skpt USING unique sketch_id' where %X% is replaced by a variable.

This is repeated for a set of 8 layers.

Basically I would like to program to operate like this:

- User accesses the URL and a general map of the world is shown (ready)
    (user specific sequence)
    - User logs in: a pull-down box for a map for that user comes 
available. a second pull-down comes available that presents the user 
with the option to select a theme ((ready, but not yet user-specific)
    - In the pull-down a default map is selected, user zooms automatic 
to the bbox of that map (already implemented; uses a view in the postGIS 
db containing the BBOX with a buffer)
    - Layers come available in the themes dialog. Default the user 
specific layers get turned on. (to be implemented)
    - User selects a theme in a second pull-down box -> a thematic layer 
should be created and shown
(end of sequence)
- User selects another map
- for the map that was already open the user specific layers should be 
removed, the user specific sequence is ran again.
- Users should also be able to switch themes

I will look  at the sample!
