If that is what you _think_ you're buying you better have in the contract
with the seller that that *is* what they're selling.

_Somebody_ has to pay for those resources, and unless you have a _contratual_
commitment for someone to provide them to you, you are *NOT* assured of having
them.  Even in today's world, -with- an adress-block acquuired directly from
an RIR, you're _still_ not 'guarantee' a DFZ routing 'slot'.

What is the liklihood that contracts for connectivity/transit/peering will
start to place limits on the number of prefixes that can be announced/serviced?

That will *really* drive aggregation.  Including attempts to 'trade' multiple
non-contguous blocks for a single contiguous one of 'equivalent' size.

This could involve some, large-scale, 'painful' renumbering,  but does have
potential to significantly reduce DFZ table size.   <grin>
