Do you take hours ratio into the account? e.g if you've been working 4h a week, then it'd be weird to say after year that you have 1 year of commercial experience, when your colleagues spent 40 hours / week and have "only" 1 year too I believe that pay is not necessary, but working for somebody else or in team (e.g OSS) is necessary. So yea, I wouldn't say that hacking something even cool, but alone is commercial xp.
