Stephen,
We have greenscreens at the Oregon Film Museum that operate on PCs. I don't know all the details as it's not my area of expertise, but you can contact Mac Burns, Executive Director ([log in to unmask]), as he should know. I do know that the backgrounds are custom and the interface we have is probably much more extensive than what you are looking to accomplish, but what our visitors create does get send to them via email rather quickly.
Good luck in your search!
