Ok, so that implies that it is burned into hardware and as it is
ASIC-based hardware and not FPGA, they can't reprogram the hardware with
a code update (one of the advantages of FPGA-based hardware).

I don't think I had general usage in mind, more along the lines of the
"middle 4" in NAT444 that will be rolled out in many networks to
conserve IP space.

The usage I have in mind would be transparent to the end stations and,
frankly, someone who produces provider gear and CPE that can take
advantage of that space is going to have a great selling point.  There
is some gold under there for someone.  240/4 is a great big "dig here"
sign if they want some of it.
