I don't quite see how this matter fits in to DFSG, or if it touches on it at all, but Berkeley DB from Sleepycat has come up with a curiosity that's new to me; they now state at <URL:http://www.sleepycat.com/licensing.html>:
The term "redistribution" in the Berkeley DB public license means your application is distributed to more than a single physical location. Installing copies of an application at different physical locations, whether they are customer sites or sites of a single organization, is redistribution. Examples of redistribution include: [...] * Building an application that you install on your company's servers in data centers around the world. I.e. your right to use Berkeley DB for free for in-house projects is cancelled, and you're obliged to pay them, if your in-house project spans multiple physical sites within your company. My gut feeling is that this is discriminatory in intent, it doesn't have the flavour of DFSG, but I can't quite find anything explicit to use to say that this should be grounds for moving Berkeley DB into non-free. -Bennett
