I don't even know where to begin.  Well, maybe here:

"The only real difficulty here is getting the right
people to act on it."

That neatly sums up the problem.

When you can round up:

1) All the programmers for all the tens of thousands of
different IP
   devices that are out on the market, have them dig up the
source code
   for these devices (some of which may have been a few
employers ago),
   and you get them all to agree to post updated copies of
their firmware,
   which might be problematic for those companies that went
T.U.,

You still have the giant problem of:

2) Getting over 100 MILLION users to all update the BILLIONS
of devices
   that are out there with that firmware.

Once you have a game plan for getting those hundred million
people to do
this, then we may have something to talk about.  Until then,
not so much.

Your "people whose technical expertise <you>
trust" clearly figured out
that there are cases where you can make moving an IPv4-240+
packet work.
Anyone can make that happen.  However, they apparently
failed to impress
upon you that what they were (hopefully) saying is that
"enabling IPv4-
240+ on a single device is a very simple technical
issue."  Deploying it 
on a wider scale ... not so simple.

What kind of customer would actively solicit an IP address
assignment
that won't reach random segments of the Internet?
