This looks very interesting, but can anyone tell me how scalable is this? All the examples I've seen are small scale; but can it support, say, 1000 clients? 10_000 ? Higher?
The framework is built around long lived requests, which push data to the client. There doesn't seem to be anything unscalable about that, since Facebook and many other huge sites are doing it.
That essentially leaves node.js and mongo, both of which should lend themselves to scaling pretty well.
