IP addresses are very valuable..."routable" IP addresses
are even more valuable...routability is determined by other
Internet participants being willing to route your traffic...if
you have a nicely aggregated block of addresses then you
are OK...if not, then you are in trouble...
Well, I am sure the InterNIC would be more than willing to trade a small,
fully utilized block for a larger block with room to grow. But I won't
mention the R word here 
ISPs will have to start "seizing" blocks of addresses from
IANA and taking over allocation responsibility to survive...
as you can read between the lines on http://www.netsol.com
no one is going to insure that your business survives...
Well, I doubt this will happen any time soon. Remember what happened to
the person who was announcing 208/8.
