we did one for them when I was at frog… forever committed to the deep storage files 
At Sound United we have used outside firms for things like this from time to time. We showed a future vision of connected home audio that we worked with Ziba on… in the end we went outside for 2 reasons:
- bandwidth. The internal team was just at capacity on production work.
- validation. For the board and others having an outside firm work on it validated the concepts we already had internally.
If I could have eliminated those two factors I would have kept it internal. The final piece was a video showing a variety of use cases throughout the home, not dissimilar from his piece IDEO did for Intel awhile back. Even so, I made sure all of the hardware in the video were designed by the internal team.
This IDEO vid is old, and a little slow, but the overall still strong, so these future vision pieces can be pretty durable.
