Thank you for this encouraging remark.

Yes, that would be necessary.  It isn't hard to tell which executable
goes with which processor.  The software vendor could give away a database
to do it.  Or, the software vendor could put all the executables up on
a web site.  What's the big deal?

Yes, I do.  (BTW, the software might be sold for the same price, but
be better in other ways.)

In the current business environment.  One reason site licenses are sold
to companies is to make piracy less encouraging.  It also solves a difficult
bookkeeping problem: "How many copies are we running?  Are we in compliance
with the law?"  Actually, site licenses don't always solve this problem,
but they sort of do.

We don't really know what pricing and terms would look like in a piracy-free
environment, we can only guess.  My guess is that preventing piracy makes
more software available for better prices.  If metering is feasible, it would
work out very well because customers no longer have to take a chance on
software and can easily explore all of the options they have.

Let's assume 10MB of executable code per package.  A gigabyte costs about
$200 now.  That comes out to about $2 extra expense per software package.

Whoever is doing the updating just needs to be able to quickly get the
right copy.  That's easy because each software module is self-identifying
as is each processor.  You just need to be able to go out on the Net
to the software vendor or internally and ask some machine for the
particular copy you need.

This is true.  Most people make their software buying decision based on
what it can do now and for the next few years.  I believe that is rational.

Yes, it would definitely be harder to keep a code museum.  People who
plan on doing that are encouraged to choose another platform and software
set.

I find it interesting that you compare this scheme to Clipper.  Judging
from the tone ("!!!") of your post, there is something about my scheme
which you find upsetting.   People usually don't get annoyed by schemes
which won't work.  (Even dumb unworkable schemes are a breath of fresh
air on this list right now.)

What I think you really don't like about my scheme is that you think it
might work and you fear various mandatory GAP proposals that could follow
its wide acceptance.  I would be interested to hear more about these
concerns.

These are not either/or propositions.  If the decrypting processor
increases the revenue of software companies, it means people can make
more money providing better products to their customers.

There is no such thing as "profitable enough."
