Is it possible to find statistics of specific computer software
products, without the company's consent. Specifically I am interested
in annual sales of commercial-over the counter & shareware software,
number of downloads of specific shareware, revenues from a specific
program, as well as any other pertinent information.

The software information should regard small and not well known
companies and software. I  am not interested in statistics concerning
Microsoft Windows OR any other well known products.

The answer should be general regarding any company or product.
