I completely understand the importance of the allocation of blocks with
as short a prefix and as consistent as possible, but thanks for the
clarification. Out of curiosity, who was the original classification of
size (/32 and /48) distribution designed by? Was it the community as all
other ARIN policies are created by?

Also, I don't pay attention to what other RIR's are doing, is this
allocation scheme the same across all RIR's?

Sounds like extortion to me. The only way anyone can profit from holding
v4 addresses in speculation is if there is demand. Someone will always
try to make a quick buck. Although * won't see any of such financial
gain, any company that we do work for won't have to dig into their
pockets because of it either.

Unfortunately, IPv6 does not have enough traction to make itself or it's
importance understood across the board. Perhaps most business are
thinking the cost is too high for the R&D at this time, but that is too
short term thinking for me. The costs of doing something later may be
far higher. What ever happened to due diligence anyway?

Another possible issue perhaps, will there be any network operators who
will filter routes that are held or were knowingly acquired 'illegally'
from a legacy holder nearer or after the runout?

My consensus from following this and other lists is that I concur with
this statement.
