Lets assume that their need is so immediate that they can immediately 
use 80% of the first /16. Or immediately enough... they can simply write 
the purchase contract to allow the transfers to be spread out over just 
enough time to achieve this (even the Nortel-Microsoft deal is written 
with subsequent transfer language)

Maybe this long, even so it doesn't matter (see above)

Exactly. For all we know this has *already happened* for some huge 
amount of the address space, and we just haven't seen the transfers 
trickle through yet.

Of course if the seller doesn't really need the space, there's not much 
preventing the buyer from starting to use it before the transfers are 
approved... which just reduces the accuracy of the whois database.

Right, which is unfair to a recipient who thinks they can only find /24s 
but then next week finds some /16s on the market that are what they 
really needed, only they took one of the /24s in desperation.
