Actually, there is quite a bit of interest already in the same circles that are using RT preempt. "How do I get a timer with better than 1ms resolution" is an FAQ on linux-audio-dev, and once you have dynamic tick the next logical step is high res timers. Currently we refer these users to George's site. I suspect the only reason there has not been more interest is that not many users are up to integrating the HRT and the RT preempt patch.
