1) There was a rumor but no time frame given. They would have to built a beoport like piece of hardware that connects the PC to the BS5 head unit.
2) No, approach right now is to recommend other solutions like Tvix
3) To use 3 cables was done to support custom installations, the product is using standard cables rather then a B&O produced one which obviously could have been thinner.
4) I would look at ATV which can be controlled through B& TVs, Tvix, Popcorn hour and Mac Mini. I don't think B&O will come around with video streaming any time soon.
