I found Ariel's proposal interesting.  It's technically fairly clean.
However, it does seem to assume that the X.400 world will cooperate
with it, and that the Internet is a fantasy network different from
the real network today.

I don't believe there is a GB Internet domain.

I don't believe there are ADMD's in the US called MA and the other
state names.

I don't believe the X.400 world will honor requests from the XA
country to be routed to the Internet.

I don't believe that all countries have set up their Internet domain
name spaces to look like OU.Org.PRMD.ADMD.Co .  (In fact, I am not
aware of any country that has done so.)

And I don't believe that this gatewaying method has already been
tested for years and found to work well in practice on the existing
networks as a pragmatic solution.

If all of these were true, and we didn't mind the funny "XA" country
code, this proposal could be very nice.  However, I'm not holding
my breath for the assumptions to become true.
