There must be some mechanism implemented whereby address space will return
to the IANA after a specified period of time unless otherwise requested by
the prefix holder.  Otherwise what will happen is that this 60% (or some
other large percentage when the figures finally settle) of the 192/8 address
space will effectively be lost from the internet with no real means of
retrieving it.  A system like this without any garbage collection mechanism
is eventually going to fill up with defunct allocations and the cruft of
years past -- something which is not an option when dealing with limited
address space.

How are the InterNIC coping with the new domain name charging scheme?  If
this were successful, a similar scheme might be considered for address
prefixes.  The legal consequences are similar if not quite the same, and
one is really no more rude or presumptious than the other.
