Simple Solution (Score 2)

I work for a small company that has mostly done contract programing. We are now moving towards a product building phase and have put together some thoughts on open source. As were are a for-profit organization we must charge for the stuff we produce. However, there has been an official management decision to make the full source to all of our [future] products (that we have licensing control over, i.e. not contract work) freely available at no charge (download from site) with no prior purchase of the product neccessary.

The framework for our developing license is this (from http://www.ipninc.com/opensource/:

Although we may license some of our products as free-of-charge for personal use, or completely free-of-charge, or even GPL'd, the majority of our products will remain under a commercial Open Source license available for a reasonable fee. The gist of it being:

• Our source code may be freely distributed as long as it remains unmodified. Community modifications to the source code must be distributed separately from our source distribution.
• In order for community modifications to be included with our source distribution they must be submitted to, approved, and distributed by us. We do not pay for community contributions
• We will never charge for any community modifications submitted to and distributed by us, but we retain the right to distribute them
• Compilation of the source for investigative or educational purposes is acceptable; Use of compiled binaries without an appropriate license is not.

This sort of license still offers the benefits of Open Source while allowing us to remain in business.

As I said, this license is still "under development" and we as of yet have no products to apply it too but we still think its a good idea.
