Microsoft, in one of their recent ad campaigns suggested that using one
of their server products ( I think Exchange, but I can't find the ad at
the moment) would reduce stress and allow the network administrator to
have more time to play Quake without interruption.

Obviously Microsoft feels that playing quake is good for the long term
sanity and health of your administrator and consequentially your
network.  You just need to show this ad to your boss and they should
understand that Microsoft recommends that network administrators not be
deprived of quake time and that should clear it for you.  If you boss
does not believe Microsoft then it is time for them to attend another
Microsoft Customer Re-Education Session.

In vague seriousness, given Quake's amazing abilities to hog processor
and bandwidth, it can be a good stress test on a network.  Start up a
quakeworld server on that big manly server of yours (it runs on NT, 95,
Sun, and Linux to date - unfortunately single threaded though) and go
start clients on high end machines across your network (up to 32 clients
per server).  Nobody actually needs to play Quake (so there is little
danger that somebody may have fun on the job) for it to start sucking
down all available resources.

I may have to go do this this weekend.  See if I can melt that new Cisco
switch...
