I believe that 2008-5 should guarantee at least some PI IPv4 address space 
will be available within the ARIN region for IPv4 to IPv6 transition 
mechanisms.  I don't see why a new entrant with mostly only IPv6 address 
shouldn't be able to get at least some IPv4 space for transition mechanisms. 
On the face of it, that is the intent of 2008-5.  If you disagree, please explain 
why, and lets try to fix that.


If in the long run IPv6 adoption fails, well then there really can't be any new 
entrants can there.
