I'm worried about the copyright of any external work I do, so I need a little advice.
What do I need from my employer to clear me to work on wine? Is something verbal ok, or should I get it in writing?
In the US, if you do the Wine work outside of your workplace, on your own time and with your own equipment, it should be okay. IANAL, but see e.g.: http://www.supnik.com/reid.htm
