E.g, suppose you're using some GPL'd code as the starting point for developing some classified analysis software. The GPL requires that you make the source code available to those to whom you distribute this analysis software. That may or may not be acceptable depending upon the security clearances of those ultimately using the software. To make this example even more extreme, consider the consequences of deploying this software in a military aircraft. Would you be willing to make the source to the software available to the pilots of the aircraft? You may wish to seek a legal opinion on the above, however, because it's not clear to me if the pilots would be entitled to the source under the GPL. Perhaps only the owners of the aircraft would be, or somesuch... If the above is a serious concern, but you still wish to use some GPL'd software as a starting point, you may wish to explore some of the standard techniques used for decoupling proprietary software from GPL'd software. If you use a piece of code based on a BSD style license, I would imagine that there'd be fewer questions. Kevin
