Actually it would - just report it as '0.0.0.0' or '::' as appropriate
for the protocol it ended up listening on. You can quite happily also
call connect() on '0.0.0.0' or '::' AFAICT - it'll just connect to anything
listening on that port.

I think this needs to change to reflect the actual address listened
on - as per above - fun escaping '::' if its a IPv6 address since we
use ':' as a field separator too :-( Do we already have a scheme for
escaping ':' in addresses ?
