Ok, here's the patch against today's CVS code.
It is a bit raw and experimental, but it can get better with your help.
As you can see from the code the patch makes crack-attack independent
from the Address Family [1], so it can work with virtually any Network
protocol supported by the socket interface... 
The usefulness of the AF-independent approach is that the application
demands to the OS the coice of the network protocol to use, if more than
one is available. I tested it a bit and it seems to work well, but it
can be useful to test the patch in a IPv4-only environment (i's not my
case) to verify that it does not break anything.

This choice can be added, of course, but maybe it can be more useful a
--bind option for the server part, to make the server listen only on a
given address, if thare are many. The -6 and -4 switches would be
trivial to implement but using them it sounds to me like breaking
the concept of Address Family Independance.

I do not know if my code works on Windows, does Windows have a good
getnameinfo implementation?

Last note: shouldn't the gui show the address(es) on witch the server
can listen? (Instead of 127.0.0.1)

Any comment?

Have a good time,
   Antonio.
