Some apps allow you to choose audio devices for input/output, but not browsers yet that I've found.  Is that what you're using to 
route to different destinations?  If I could choose devices, or configuration of devices in this case, on a per-tab basis, that 
would be very cool.

They alternated between real 5+1 for a movie and with a test pattern and then simulated it with headphones on a Qualcomm tablet.  You really had to take the headphones off to prove to yourself that it wasn't coming from the same room speakers.  Spooky good.  They perfectly matched the performance of the room.
>> And all video players, including TiVo and imitations should have 1.25x, 1.5x, 1.75x, and 2x speed up options, with normalized sound. Ideally, speed should be variable based on action, pacing, and speech density.  You couldn't speed up House of Lies at all, or Newsroom, but most sitcoms would be comfortable at 2x.  I became addicted to 1.5x using VLC for Stanford MOOC classes.
