No, mod_throttle is now completely ineffective, since Netscape NATs 
everyone coming through the firewall to a single IP address.  I asked 
the author of mod_throttle about whitelisting, and he said it'll happen 
in versioni 4, due out sometime (this seemed to be later than sooner).

Fortunately, however, John Dee has agreed to work on a script that 
accomplishes what mod_throttle does except that it creates permanent 
bans and honors a whitelist, so we should have better defenses against 
these attacks soon.
