Presumably everyone here has read the recent issue
of the Cisco IP Journal which has some data to back
up what Randy is saying.

I don't believe that this will happen. End host operating
systems have had IPv6 for several years now. When the IPv4
space is exhausted, the vast majority of end-hosts will be
capable of running IPv6 by simply enabling it, or installing
an add-on package. Of course this does involve some effort
but the magnitude of the effort is similar to patching 
operating systems after the latest worm/virus outbreak.

I'm sure that there will be a frantic scramble, but I don't
expect it to last long enough for an IPv4 black market to
form. Also, I would hope that the RIRs have a formal procedure
in place by this time so that IPv4 addresses can be returned 
and recycled.
