  That's great for Ford or American Airlines.
  That's totally ridiculous for linking the 7 locations of
Bob-DryCleaning's together over $200 VPN.
  Perhaps tunnelling IPv6 inside IPv4, without the help/knowledge of
the ISPs.

  The big guys do not have a problem --- look the government of germany
just got a /26.  No big deal for them to parcel off a /32 for use on
some COIN.

  It's the small guys that will have a problem --- and it will be the
small guys that will deploy useful things first.
