I think that won't solve Joe's problem, since this just pushes the 
problem back, from "knowing all IP addresses" to "knowing all interfaces".

I've still got a nagging feeling that Joe is on the wrong trail. 
Applications should never be required to chase for IP addresses (or, for 
that matter, for domain names).
Of course I might be wrong - I'm not an X guru, it's just that I've been 
setting up my Linux box in the past weeks and learned more about IP than 
I ever wanted ;-} (and, of course, in a haphazard manner so it's easy to 
overlook some details).
