If I remember right, camtasia.info was in this formum a week or so ago. It's the name of a software and is trademarked. It's a great name, but you may have the TM to deal with if Techsmith (the parent company) pushes it.
polkamusic.net might be valuable to an oom-pah band...or maybe an online download service for category music. Don't think it's big time bucks...best case: $100, probably less.
