Entrepreneurial Idea?

I was thinking tonight about items that have big prices but can be shared among consumers. For example, computer programs such as Microsoft Office or the language learning program Rosetta Stone, are both on the expensive side as far as single consumers go, especially if neither products will bring with them monetary remuneration.

But, perhaps, a Craig's List of sorts could be set up for isolated consumers wanting to go in with other consumers on such products? For instance, I want Rosetta Stone French and RS German, and I'm sure another consumer SOMEWHERE in the world wants to do the same, and the RS software can be used twice. Not only would this 'sharing' cut the $600 price in half, but also both me and the other customer would be less willing to rip an illegal copy off the internet. Thus, both consumers and producers are made better off.

Of course, how many consumable goods can be duplicated in such a way as computer programs? I can only think of things like Photoshop, Office, and Rosetta Stone. The products have to be duplicable. I think.

Either way, this idea does set up an information exchange, which is essential to markets. I think it would work, though it would not necessarily bring in big profit margins to the host of the exchange. Would some products be made so incredibly accessible to previously isolated consumers that product prices would rise substantially? No telling, but I like the idea.

Hmmmm.
