Ok, here are some reasons:
- you can have more simple firewall rules.
Don't underestimate, they are getting complex in bigger networks.
- you can block other programs like icq.
Only way of really blocking things like icq I can think of is
by changing dns resolution for these hosts. simply done on the proxy
server and not for the whole network.
- simple squid acls I already mentioned
- I trust squid/linux more than windows in any kind of network operation

- you can prevent users from reenabling proxy settings easy
- proxy settings are delivered to the client by our novell server, no
need to do this by hand
- users are not allowed to go directly, this was just a test, but I
already mentioned that, sorry if that was not clear.
- authentication does not work with transparent proxy, we are currently
not using it, but will in the future
