It doesn't matter what version either. The GPL states that free software is free for all use, personal or commercial. Changing the license for HFSLIP would not be possible without Tomcat76's approval (if so inclined to do so, anyway). Personally, I'm a fan of the GPL, but for my own projects, I usually chose to use a Creative Commons license, such as this one: http://creativecommons.org/licenses/by-nc-sa/3.0/ which prevents commercial use. Perhaps switching from the GPL to a CC-like license would solve the 'problem'. Then again, HFSLIP has helped me out in non-personal uses, which I only used since HFSLIP is licensed under the GPL! So, I believe that anyone that uses HFSLIP under its current GPL license, has the right to use it for personal and non-personal uses. If the license should change, then that's a whole other story. Putting language in stating that the program is INTENDED for personal use only is more or less a reminder that the software developer provides NO warranty for the software. Just my 2 cents on this topic. I've been wary of speaking about it, in case I offend anyone. I'm just stating facts and showing how to 'fix' the problem, if the community is inclined to do so.
