Assuming they can find it. You presume there are options available to
organization A that I'm somewhat skeptical will actually exist. There
will always be incentive to minimize the number of number of blocks
being announced if you have to go out and find those blocks and then
convince your ISP(s) to actually route them so if folk are having to
go find address space, they're presumably doing it for a good reason.
I suppose we'll see.

Will review and comment, hopefully by Monday, but I would point out
that people go to the purely black market today so the restrictions
folks face today would appear to be too onerous. Adding vast tracts
of new regulation would seem likely to increase the number of folks
forced into the black market.
