How far in advance? Would passing an argument to play() satisfy this? 
(i.e. can it be immediately before playback begins, or does it have to be 
measurably earlier?)

With the proposal, I don't see how you can set the speed in one controller 
and then have another controller do fast-forward and then have the first 
controller resume play again, which is a design requirement for this API.
