Be very careful with intellectual property issues. Make sure you decide what part of the work you'll do belong to you or them. Discuss that with them upfront, in a diplomatic way (so you don't sound too pretentious). That's very important if you "think" the open source way, where we can share some stuff. Some people are absolutely against that mindset.
