[K12OSN] Setting a default, non-customizable desktop

[Richard K. Ingalls]

The language arts teacher (who has a 10 client LTSP lab) told me today 
that the 8th graders were changing their backgrounds, and she doesn't 
want them doing that because a few have chosen pictures that are 
pushing the limits of appropriate for a public school (k-8 grades).  I 
told her that I allow them to customize, but that it must be 
"appropriate" for public school.  Of course the real problem is 
defining what is appropriate (for today's 8th graders who have been 
brought up by MTV -- it is not the same as for me).  Anyway... I digress.

How can I make it so that my users have absolutely NO CUSTOMIZED 
DESKTOPs?  Is this possible?  If so, what must I do?

If I have to make a threat to my 8th graders to "clean up their act" 
or else I'll do it for you, then I need to be able to back it up.  At 
this point I can't, because I don't know how.

Any help out there?
