What makes your DoS interesting is whether the attacker needs
a lot of bandwidth or not.  Ie. if he has to be sitting on your
gigabit subnet then the attack isn't interesting.  Whereas if he
can eat all of the remote systems cpu cycles just being behind a
cable modem, that's interesting.

Which is it?

Also have you done your cpu utilization tests on something a little
less ancient than a 450mhz system?  How fast was the network?
