Independently, without seeing this thread, I had already posted this today: https://news.ycombinator.com/item?id=8563103

I would definitely participate as a contributer, if it's open-source. I'll email you.

By the way, I have already tried Meteor which relies on MongoDB. However, Firebase allows you to read and write data at any arbitrary location. MongoDB, on the contrary, expects you to have some basic "collections" and write complete documents in there. Anything that is on a deeper level inside is called "embedded document" and the support for common operations is much worse.
