As for streaming it to another player, that's not possible.
You'll likely need a monitor to navigate the Pandora menu, but further remote control of that specific interface isn't possible (ie: From Blu-Ray through network to another audio device).
i am wondering if there is a way to access the BP-P1600 via a web interface?
I don't have it hooked up to a TV right now, but want to listen to some Pandora. Anyway to remotely control this unit?
