That helps, but I guess it begs the question of why you would want "10 processes asynchronously responding to one browser"? And what does that really mean?

It doesn't sound particularly useful for traditional HTML responses (unless you had some kind of simple template system to aggregate them into a coherent response), but I could see it being interesting for WebSocket applications, especially multiplexing multiple backend services over a single connection. For example, on Facebook's chat and news feed services multiplexed over one connection. Is that a typical use case?

It would be really awesome if Mongrel2 could support something like Socket.IO or Orbited, which provide a WebSocket-like API to the browser, but automatically negotiate another transport if WebSocket isn't available.

Maybe it already does, I don't know. I'd just like to be able to use something like WebSockets without worrying about the capabilities of the browser or backends (Socket.IO is for Node.js and a few other platforms. Orbited seems like a dead project, but I believe it used the STOMP protocol).

Two use cases: A background task that involves a few systems, but you don't want to block the main app stack. Simplest case is say image crunching on an upload. More complex case is what you'd do with something like Gearman.

Second: You can carve up your pages into each piece and plug the pieces together. This would require a bit of coordination, but you could have a backend for headers, one for content, side bars, footer, etc. and they all respond when they get results directly to mongrel2's socket with a chunked-encoding.

It already supports Flash sockets and long polling, so Socket.IO should just work. Haven't tried it though. Check out the docs and look at the chat example in examples/chat/ for a quick (slightly old) demo that's just using jssocket.
