if you look at the recent ipv4 burn rate of ripe and apnic
especially, we run out of v4 space in about three years. 

Presumably everyone here has read the recent issue
of the Cisco IP Journal which has some data to back
up what Randy is saying.
http://www.cisco.com/en/US/about/ac123/ac147/archived_issues/ipj_8-3/ipv4.html

four years from now, when marissa can't get v4 space from an
rir/lir and so gets v6 space, she will not be able to use 99%
of the internet because no significant number of v4 end hosts
will have bothered to be v6 enabled because there was no
perceived market for it.

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.
