Yeah, I thought of that one too, but "usually" (at least
that's what is instinctive to me) you bind to INADDR_ANY
or ::, so this only becomes an issue on the client side. 
(And there, most people put the -4 or -6 before the address,
but I agree it would be nice to fix this..)

sure, I can put that out on V2 later this week.
