If you have anything that is trademarked in your domain you can expect a cease and desist letter. When starting out I made the mistake of registering domains like RolexPoker.com and PlayboyCasino.com. I never developed them but still got requests from the legal departments.
Other notable legal contacts in my life would be Harrahs and MySpace.
Learn from my rookie mistakes and don't even waste your time. As long as there is no trademark or copyright you should be fine.
