Interesting, thanks. In that first blog post it mentions that Meteor serves static files. Is that a requirement?

edit: posted too soon they talk about it here https://meteorhacks.com/does-meteor-scale.html

And you can use cloudflare or some other CDN very easily. See: https://meteorhacks.com/cloudflare-meets-meteor.html

No, it is not a requirement. Meteor also supports serving static files from a CDN.
