Play on two devices at the same time?

[nickfiore]

This is likely the wrong forum, but I can't quickly find any other areas that accept posts: I use spotify as a music source via my iphone and play it though a Bang & Olufson "playmaker" connected to powered speakers.  I also use have an ipad mounted in a Bang & Olufson "A3", which is simply a frame with built-in speakers with a recess to hold the iPad securely.

My question is: is there a way to use Spotify to play on both devices either alternately or simultaneously?

@nickfiore You'll only be able to play music online on one account at a time. However, with playing devices alternatively, Spotify Connect may be perfect.
