Carrying on from #262. Just opening this so anyone interested can follow along.

Generally anyone working with streams is going to use that library -- it's like the jQuery of streams (I hope this is quoted on their readme someday). We could write out our own object stream, but we would end up with a lot of code that isn't important. Plus, it's good vibes to show how we can be used with other popular OSS libraries.
