Hi John,

Without a globally coordinated policy there are no transfer common
requirements, just the combination of the requirements applied by each
registry independently. I'm asking that the combined requirements of
all registries in the sequence (combined, not common) be met at each
step of the transfer sequence. In particular, the transfer should fail
if the combined policies are self-contradictory.

An example: a transfer which involves both ARIN and CNNIC somewhere in
the sequence should fail because ARIN requires transfer reciprocity
while CNNIC refuses out-transfers altogether. Introducing additional
transfer steps in the middle of the sequence should not make such a
transfer possible.

Call it a long hold timer before the sequence is considered complete
and a new transfer can start without considering the whole chain of
registry policies.

That sounds about right. With more than 3 or 4 registries in the
sequence a transfer would be hopelessly complex, hence blocked.

Clear reference approach = globally coordinated policy, yes?

Even if successful, that'd leave the problems with section 8.4 in
limbo for an awfully long time, would it not?
