Trademark is probably your best bet. If they haven't used the name, you're probably out of luck. You can take it as a badge of honor that someone liked your idea enough to copy you. I've had one of my iphone apps copied, not quite as thoroughly as you say, but enough to know that I inspired them. I say, have at it - if they're making the same kind of money I am from it, it definitely cost them more to make than it's worth. ;-)
