I hope that WRI is not going to stand pat with that solution. There are many
drawbacks.

1) The last I heard the free Player could not use third party packages.
2) One has to send everything to WRI to get 'converted'.
3) Having bought the expensive Mathematica, one should be able to sell
notrbooks, say, without obtaining an additional license from WRI. (Does one
have to obtain an additional permission and license from Adobe before using
PDF documentation in some computer software?) In any case, most the use
would be in scientific communication.
4) Allowing Premier subscribers to distribute only two Mathematica
PlayerPros is too restrictive. And, in any case, we have no idea how one
does that.

Perhaps it is a serious technical problem to produce a free Mathematica
player along the lines of Acrobat reader that would protect the basic
Mathematica property and be a viable business model. If it can be solved it
would be a major completion to WRI's core technology. People really do want
to communicate via Mathematica notebooks.

I think it would be good enough if all the reader could do is evaluate a
notebook and operate dynamic controls. Some of the restrictions, if these
are possible and there isn't some essential impracticality in it, that might
limit the ability to hack could be:
1) Don't let the reader print or save the notebook.
2) Restrict InputFields to number data.
3) Restrict keyboard entry to those forms that are necessary for evaluation
and operating controls. Maybe no alpha keys. Maybe someone could arrange for
a reader to click characters off a palette, but that is very inconvenient.
4) Restrict the amount of keyboard entry in a session.
5) Don't provide Mathematica documentation and don't provide it online. No
basic palettes either. Don't people who buy Mathematica get the
documentation with their installation and can't they update it?

Maybe these kinds of restrictions wouldn't be sufficient. I don't know. WRI
already provides significant free use of Mathematica through the Integrator,
and through Wolfram|Alpha. It seems that a Mathematica Player wouldn't have
to be more airtight that that.

If people started receiving nice Mathematica notebooks and reading them I
believe they would be impressed. They would want to be able to generate the
same kind of documents. Nothing would do more to spread the use of
Mathematica and increase the customer base. Existing users would be the best
free sales force you could get.

Mathematica as a communication medium is a better business model than paid
links on Wolfram|Alpha. It's a better immediate use of the core technology.
It would be a revolution in scientific communication.

Right now, Mathematica is a very expressive beautiful bird locked in a cage.
Let her fly free!

This would be a good application of the free Mathematica Player.
Player is not just for powering http://demonstrations.wolfram.com

If the material is supplementary to the book (IE freely available),
then it could be converted freely for use on Player at
http://www.wolfram.com/solutions/interactivedeployment/publish/

If the content is to be sold, then you would need to talk to Wolfram
Research about a special license to use it commercially. But this
could be a one time as part of publishing, and not something that the
end user need know or care about. For the end user, it would just be
part of the book.

Apart from this licensing difference, the differences between
Mathematica Player and Mathematica Player Pro would probably not
matter to the project you describe. They are listed at
http://www.wolfram.com/solutions/interactivedeployment/compare.html
