I did not get a chance to test this but it may be a 50% solution. =20
--Create a folder under the account used by students.
--Set this folder as the download location for Safari and Firefox.
--Log in as an administrator and change the access privileges to the
folder so the student account no longer can access the folder (i.e. make
owner, read and write permissions admin only). These instructions will
give you the basics.

When a student starts a download they should get an error and the file
should not be downloaded. This is not an ideal solution and it is
easily circumvented but it might suffice to limit the issue until you
find a better solution.
Some firewalls, content filters, and proxy servers will also allow you
to set up special rules for individual machines that allow you to block
specified file types. This may be the case for you as well and would
probably meet your needs if you are only trying to conserve bandwidth.
A true traffic shaping/management solution would be the ideal step (i.e.
packeteer, cymphonix, etc.) since you could prioritize traffic rather
than blocking it completely.

Subject: Blocking Downloads
Does anyone know of Mac product that will block files from being
downloaded? I just want something that is for a couple computers, not
for a network. I turned off admin access, so files can't be installed,
but the kids can still download them.
I am using Firefox, but I can switch to Safari if needed.
Thanks,
Renee
