Firstly, use `require('stream').Stream` for backwards compatibility with
node v0.4.
Look at the stream API for the methods and properties that you'll need to
add to your class for it to be a valid stream.
http://nodejs.org/api/stream.html
Write streams can have the pipe methods if they are also a read stream. And
if not, you can listen to the `pipe` event and throw an error if it's
called.
If your event emitter emits `data` events and it's all it does, there's
some modules that make converting it into a stream easier
