 not technically possible.

 Well they might.  Well, actually, poorly they might.

 But that argument seems to play right *to* the alt-root operators,
 since the "fix" is to switch your customer resolvers to point to one of
 them.

      I disagree.  The problem is that there are too many alternatives.

To many alt-roots?  Or too many alt-TLD's?

        (Assuming, of course, they stay supersets of ICANN, and don't
 get at cross-purposes with one another.)

      The problem is that they are pretty much guaranteed to get at 
cross-purposes.

Well, there have been alt-root zones available for, what 6 or 7 years
now?  And how many collisions have there actually been in practice?  2?
3?

                                           In fact, merging them at your
 resolvers might be the best solution.

      I don't think that's really practical.  I'm sorry, I just don't 
trust them to write a resolver that's going to get included in libc 
(or wherever), and for which the world is going to be dependant.

Well, I meant "at your customer recursive resolver servers", since the
topic at hand was "what do IAP's do to support their retail customers",
but...

      The alternative roots will always be marginal, at best.  The 
problem is that while they are marginal, they can still create 
serious problems for the rest of us.

In the context which people have been discussing, I don't honestly see
how they cause "the rest of us" problems.  People with domains *in*
those aTLD's, yes.  But as I noted somewhere else in this thread, the
only people who would have un-mirrored aTLD domains would be precisely
those who were evangelising for the concept, and it would be in their
best interest to be explaining what was going on...

 But Steve's approach doesn't seem to *me* to play in that direction.
 Am I wrong?

      I'm not sure I understand which Steve you're talking about.  Do 
you mean Steve Gibbard, in his post dated Sun, 3 Jul 2005 22:20:13 
-0700 (PDT)?

I did mean Mr. Gibbard, yes.

                If so, then each country running their own alternative 
root won't solve the problem of data leaking through the edges. 

"Data leaking through the edges"...

People will always be able to access data by pure IP address, or 
choosing to use the real root servers.  Push come to shove, and the 
real root servers could be proxied through other systems via other 
methods.

"Real" is *such* a metaphysical term here, isn't it?  :-)

      The reverse problem is more difficult to deal with -- that of 
people wanting to access Chinese (or whatever) sites that can only be 
found in the Chinese-owned alternative root.

Stipulated.  But whose problem *is* that?
