 Martin.  there is no exaustion here... there is full utilization.
	the trick here is to recast your thinking ... utilization is
	not when a block of size foo is released by ARIN (RIR) to an
	actor.  this has been the historical metric (IANA will exaust
	when the last /8 is handed over ot the RIR) and is a false measure.
	the RIRs are using HD ratios to measure utilization, which is 
	a somewhat better metric, but even that might be too ambgious
	going forward.

	once all the v4 space (as measured by /8) is fully utilized, its
	wise to change ones thinking. and we sort of have... by moving the
	utilization metric to a /22 or /24 (depending).
	using that technique, we still have some (perhaps a lot) of v4 space
	left.  but soon we will be in the postion where 
	all the v4 space (as measured by /24) is fully utilized.  but I'd make
	you the wager that there is still a whole lot of unused /28 and longer
	space that is fallow.  

	then the question is, how to squeeze better utilization out of the free space
	to aid in transtion?

	are /31 blocks of v4 space useful/usable going forward?  I'd say yes, but
	thats not a currently popular POV.

	so..  we are not exausting, we are (or should be) shooting for higher
	utilization of the space.
