        I think the point is that (despite everyones thoughts
that use it) IRC is not considered a super-important network service
these days.  If the irc server is dampened or the attack can't reach it
it just penalizes the compromised host(s) network(s) more than the
person who hosts the irc server.

Get a box, and run Zebra BGPD, which will announce that /24 to your 
network.
Then do a script which monitors the traffic to the irc server, and on a
certain threshold, kill BGPD. wait a certain time, like 15minutes or so, 
and
restart BGPD. It would be nice to check the traffic every minute and if 2
consecutive checks are positive kill bgpd. That mean that you  may be able
to STOP dDoS to irc servers within 2-3 minutes...
