A colleague and I maintain the computers in two math classrooms (31 
computers in each room), in exactly the manner you suggest. We installed 
Mathematica 6.0 after classes ended in May, before summer session, did 
some other tidying up, and sent out a new image.

We usually set most software not to look for updates (and then just 
update everything the next time we are going to make a new image), but I 
don't recall whether we did that with Mathematica 6.0. In any case, we 
haven't had any problems with it. Either it's not looking for updates, 
or it's silently installing, or silently trying and failing to install 
them. We're not seeing any permissions errors.
