	As one time member of the IANA team under Jon and the original
head of the reclaimation efforts (we recovered ~30% of the total address pool)
i'd like to clarify what the IANA did to "invalidate any IP assignments once it 
is determined the the requirement for the address space no longer exists."
What we did was:

	) contact the listed resource holder(s)#
	) ask if they were still using the space
	) if so, process any updates they provided
	) if not, markt he space as "fallow" - leaving it usassignable for a period

# in some cases the organization no longer existed, in some cases the contect had died.

	The primary reason for the LRSA, imho, is to ensure that there is an 
understanding between the resource holder(s) and the current registry. I'm all in
favor of retaining the origina terms and conditions, inso far as is feasable/legal
The fact remains that we are temporary users/stewards of the resources and that in
100 years, it is unlikely that either ARIN or any of us will be around to assert rights
under soem previous centurys  half remembered expectations. And given the surprizing 
longevity of IPv4, I think it is prudent to re-sync the understandings btwn registry and
