Sure. I want a git server with push notifications. Two lines with the pushover module in node.

I would be pleasantly surprised if this existed at all in the Haskell community. Even more so with two lines of my own code.

I think that has much more to do with the size of Node than the methods of streaming being used. Such things are easily accomplish able atop libraries in Haskell, but pushover hasn't been written as a library because the ecosystem isn't at the point where it specializes so far yet.

But the API provided is trivially replicated, and, yes, easily built atop pipes.
