xMarks - Wordpress Management Dream Solution?

Has anybody used xMarks for Wordpress Management? It looks like a high end management for massively creating Wordpress blogs on different hosts, domains, IP’s, etc. It looks really complete. Does anybody have anything to say about xMarks? I am thinking about using it for my network of blogs, as well as expanding on that.

Check out the video (full screen it) on their page and you’ll see what I am talking about.

Thanks.
