 i had a bet w/ some folks when RFC 1918 came into existance.  I postulated
that it might be better for the "Internet" if the RFC 1918 space was used to 
address the "public" Internet and the rest of the space be used inside folks
walled gardens...  circa 1996 or so.

something like this. don't even need to get rid of BGP, just add some
extension, we see ok to add extensions to BGP to do other things, this
makes at least if not more sence.

So, jump through hoops to kludge up IPv4 so it continues to provide
address space for new allocations through multiple levels of NAT (or
whatever), and buy a bit more time, or jump through the hoops required
to deploy IPv6 and eliminate the exhaustion problem?  And also, if the
IPv4 space is horse-traded among RIRs and customers as you allude to
above, IPv6 will look even more attactive as the price and
preciousness
of IPv4 addresses increases.

No problem,  everyone tunnels v4 in v4 and the "outer" ip address is
your 32-bit ASN and you get an entire /0 of "legacy" ip space inside
your ASN.  Just need to get rid of BGP and go to some sort of label
switching with the border routers having an ASN to upstream label table
and there ya go. Oh, and probably create an AA RR in DNS that is in
ASN:x.x.x.x format.  Increase the MTU a little and whammo!  There ya go!
Done.
