It was something I came across with the GNU license, which many people use for open source development. Where I work we had our own license drawn up by experts which covers our particular oddities. Writing your own license does solve the problem as you can say whatever you want. I have come across a number of forum posts recently that advocate the BSD license over the GNU license. For my own free stuff I just put in a "use this at your own risk" disclaimer. That way I can use it at my own risk in a non-free version and license that completely differently. The issue is more to do with making your source code available, or not, than anything else. If you have knowledge, let others light their candles at it. Margaret Fuller (1810 - 1850)
