That statement I think will be very helpful to me.

The push would control the buffer, creating that value concept, 
where the buffer is flush which creates a pull, specified in the 
delegate.

Pusher(buffer) <- put(content)

An output range wrapper would provide a push interface which 
would fill in the buffer of the Pusher. When the buffer fills the 
range wrapper would ask to release which Pusher does by calling 
the delegate.

Hopefully I'm following this correctly.
