both are important.  but I think the human interface is more difficult.

machines need to know how to translate IDNs from whatever
encoding they use into unicode/10646 (for queries) and back
(for address lookups).  

I'm not expecting machines to "go to" unicode in general, at least
not anytime soon.

perhaps, but this would be as a matter of policy, rather than as a 
constraint that is wired into the IDN protocol.
