I do work for one of those "large cable companies" and no, 240/4 is not
useable for us either for the exact same reasons that you pointed out to
explain why 240/4 will not work in public space: there are just too many
devices that can't easily be upgraded.

Alain,

Correct me if I'm wrong, but Comcast started moving to IPv6 addressing *because* they ran out of 10. space.

My 0.02: Hacking together IPv4 solutions involving retasking previously reserved address space simply delays the inevitable exhaustion of said address space.
