Hi John,

Plus recursion. I don't want to see Y in R acting as a proxy for Z in
S in order to evade S's noncompliance.

If we're going to permit ARIN region resources to be played on a
global field, we've a right to at least insist it be a level field.

Party X has no shortage of other candidate buyers while party Y can
petition his registry to join the "free trade pact" if he finds
fairness as desirable a trait as I do.  Meanwhile parties A through W
aren't placed at unfair disadvantaged by the behavior of Y's registry.

I'm not sure that's how I'd characterize the _failed_ experiment at
having ISPs set route filters based on the RIRs' specified minimum
assignment size in a /8. The only filter size that stuck came from the
number of bits in a class-C netmask, something the registries had
nothing to do with.

I'm not sold on that argument but I don't dispute it either.
