And just how does one telnet/ssh/smb/http/whatever to another machine via  
MULTICAST? You don't. Locating the machine isn't the issue; having an  
address that can be trivially determined as "local" is. ULA would work,  
but you'd have to know to use that address instead of any global address.

Right. So every "home user" (read: grandmother) should request their own  
PI space, that they'll then have to tunnel to a far more expensive COLO...

PI space is useless to residential customers because no residential ISP  
will ever bother with the headache. (I never liked dealing with business  
customers here, and they were paying a lot more for the privilege, and  
presumably had a clue.)

ISPs do it right now for IPv4; and it makes them real money. They're not  
going to want to give that up.  You don't, and that's fine. But I can  
assure you the suits what to keep cashing those checks.
