Nice list, one I always ask,
Also I like to clarify posibilities to bring in hobby projects if the company can benefit from it, and how the reward will be.
In one case they said that what I do in my spare time on computers, are theirs, and no reward on the other end - which I think they would have a legal problem with since it is my time off, not theirs. Needless to say, I turned down the offer :)
You should be a bit careful with that question though, if the potential future employer thinks that you are doing competing activities, there can be big problems down the road.
