There would be a subscription, but it would not need to cost much at all. It
would not have to be a significant barrier. it would probably be part of an
overall subscription that included software updates, etc. As should know, MS
is moving toward a "software rental" model.

Right you can get maybe a factor of 10 or 15 that way. Spammers would need a
factor of thousands. Also, of course, people with slow machines could be
required to put in 10 times as many cycles... it would just be one more
downside to a slow machine... probably still one that would be unnoticed,
however.

People are already upgrading their hardware for other reasons. Those that
don't are penalized for it and this would be one more penalty.

That is totally incorrect.
