One question: Why go for Rails + Pusher? Seems to me this is something that would be a perfect example for something to be ran on NodeJS.

Not to swing the Rails vs Node debate here. Pure curiosity. I've started my first Ruby/ Rails4 project for a lead fulfillment /support / admin of all sorts related backend, and building this in Rails seems like a clear choice and a blaze compared to any PHP framework.

But now as I'm starting to think about APIs and real-time presentation through WebSockets, it feels to me this stuff has not matured enough in Rails to do this easily enough without needing a 3d party like Pusher (?) (I've been looking at tubesock but it seems minimal). In other words, the Rails+puma+pusher serer seems redundant to me if you would have used Node. You do seem to make a clear statement about using MongoDB for "web scale". So I´m wondering why you would want to go the Rails way for a one-page app built for and relying on concurrency.
