There is no free software copyright law. There is just software copyright law, which allows copyright holders to distribute software under a wide variety of licensing schemes. The same law applies irrespective of the price. Read the license. Unless that is forged or contains illegal terms (unlikely), it basically defines what you are allowed do with any piece of software. If the license is unclear about matters of concern, find out what the law says about them. If the law is unclear, don't expect easy answers. (Although do be aware that sometimes people claim the law is unclear when it is not.) Perhaps you can claim that you were merely showing him, in confidence, a pro forma version that might be released at some future date. What does your mutual correspondence indicate? If the above is not the case and your license does apply, I assume from what you've said that you have granted him permission to distribute your code in whatever form he wants along with his own, while you may not have a right to distribute your own modified version, as it is based on his. Probably not what you intended, but you wrote it. Whether you have a right to distribute your modified version in certain circumstances (has he confirmed your copyright in a derivative work by using it?) just might be one of the few things that are unclear in copyright law - I don't know! Anyway if he does this, it is up to you to decide what moral or other legal leverage you can exert. - Gerry Quinn .
