First, I have to say that this looks ambitious. There are some pretty exciting things in the gameplan; I am especially interested in the vmcasts idea. While I have to wonder if they can accomplish all of the ideas they lay out here, given the posts I've seen from catonmat.net before, I think they can do it. From what I can tell, Peteris is not just clever, but very motivated and loves to code and introspect his talents. This is usually a winning combination.
I am excited you decided to open everything, but I wonder if you're going to be able to raise the money necessary to fund the infrastructure. Do either of you have a lot of business experience? If you can seize your opportunities well enough, you can probably monetize your idea while letting others do what they will with the code.
Looking forward to see how this evolves.
