Short short Summary: No better Idea, at least for our specific Situation.

Longer Summary:

1) Firewalls with User Authentication
   [Not an Option as we don't control the Network ... yet]
2) Use Caches
   [We do. We run out of Workplaces, not Network Bandwidth]
3) Use political Approach
   [Unfeasible as we're bound to keep the Hosts publicly available due to
   special State Funds used, and the Rules on what we're allowed to do
   to keep the Machines "usable" aren't defined *at all*. And the Users are
   Students, not Employees whose Boss I could convince]
4) Have People forced to go over slow Connection
   [Nice Idea. :-) But see 1) and 3)]
5) Browser/Cacheing Server/Firewall Combo
   [See 1)]
6) Have Cacheing Proxy log Requests and hope to intimidate Users
   [We don't control our Cacheing Server, either]
7) Block "Fun" Sites
8) Change Permissions
   [Doesn't help, as FTP is unrestricted, same Reasons as in 3)]

We meanwhile have the Netscape Killer Daemon running, and hope that
the average User won't find out the (pretty obvious) Holes in that
Plug ... :-C
