The biggest issue I see with this is: MongoDB. Anyone who worked with serious SQL databases who looks at MongoDB shivers. It has not even solved problems 'classic' databases have solved for over 20 years. The entire "it is fast" thing is based on very smart Linux disk-caching strategies. It's reliability is questionable. It might work very well for you, but when it would go wrong, good luck! Also I hate being tied down to 1 database back-end. At least make it a plugin or smth. That you use a NoSQL db for rapid prototyping, I do understand (although I don't like it), but you can do exactly the the same with Postgres 9.3 with the JSON extensions, and more. That way you build on a reliable, proven database which has solved the problems MongoDB is facing now a LONG time ago. Oh, and the 'big data' argument for using NoSQL is plain bullshit, only a very small percentage of developers actually have worked with 'big data' that requires clusters to process. Don't get me wrong, better frameworks are good, and I would be interested in Meteor if it wasn't for MongoDB being tightly integrated.
