Er... Have you tried it? There is nothing (that I can think of, just 
now) in the code that relies on the "dotted quad" format of an IP address.

The fact that I use '0.0.0.0' in Listeners.pm is simply because I am 
deeply conservative (I have been writing programs since 1972, after 
all). Anything you put there will simply be passed to the perl network 
routines which (usually) just work. Same in connect scripts.

Another thing you might not be aware of is that using the form '0.0.0.0' 
means "listen on all interfaces" and that AFAIK includes IPv6 ones.
