I know you probably didn't mean it to come across like it does, Timo, but I find the notion that the European Space Agency would require American funding to develop a manned spacecraft capable of repeated use really quite insulting.
Why? Europe has never had the financial commitment to see a manned spacecraft program through - it's a project that offers zero or negative financial return, after all. And there aren't too many other reasons to do it, either. The only way I could see it happening within the next ten years is if somebody from the outside offers to pay good money for it. And the Americans in their upcoming predicament are the only ones who might possibly do that.
