They look sweet! Post back when you've go thtem paired.

I think the cables on that page are audio separate female L & R to single male 3.5mm, not audio-in-female + audio-out-female to audio i/o male. Therefore, audio-in would not be possible even though audio had been separate from video. Like your thinking though.

Interesting to know. So, apart from trying to handle an extra task, the stutter is propbably because of a forced change in speed, right? Interesting.
Why is tv-out required with sound i/o? Well, when tv-out isn't for tv! As good as it is to have a h/w kb and touch screen, for word processing etc a mini office office is required: tv-out to a pc monitor and input through a BT kb & mouse. This still leaves the audio to take care of. The best suggestion so far is to use something like Nokia's BH-905.
Can anyone think of a better idea?
Also, is there likely to be any interference b/w BT devices?
