FOSS for Profit?
gojomo: Read the license. If it's one of the usual "open source" licenses, for-profit use of the software is allowed. (It's not considered 'open source' if it discriminates against for-profit uses.)Perhaps you also mean whether the software can be included in your for-profit, for-sale, possibly closed-source product. The answer is still 'read the license'. Some licenses are OK with that reuse, others aren't.If you're wrestling with subtle GPL interpretations or 'copyleft' clauses you'll want to read more of the way these things have been interpreted in the past. But there's no shortcut beyond reading and understanding for yourself, and it's not so complicated it needs paid-professional interpretation unless (1) you're with a giant risk-averse bureaucratic organization; and/or (2) you're trying to pull something fishy, far from the usual interpretations. (eg: "Is there some loophole way we can structure our code to include GPL code without making our entire product GPL'd?")
