You don't sign anything without your lawyer looking at it first. Then bring up that you do volunteer work, which may include thing like maintaining the website for your home owner's association, things like that. So have your lawyer counter with language designed to protect the non-profits that you may volunteer at. Then any open source work you do, assign copyright to the FSF (them being a registered non profit), and you are covered.

Also, these employment agreements use the words "inventions, innovations, or ideas". Can any lawyer-types chime in if that implies patentable items, or does inventions legally cover copyrightable creations?
