I want to see this in action first before believing to "press releases".
I'll believe it when someone will produce "latencytest-like" diagrams on a
heavily stressed box.
Of course to achieve this kind of latencies you do need to write windows
kernel modules with all the related disadvantages ..
See gigasampler: it's a really nice sampler and squeezes out the most of
win95/98 but I seem to recall that they are having big troubles to port it to
win2k/xp because it is programmed too close to the hardware.

RELIABLE 2-3msec (under Benno's ultra-heavy typical load) is possible on
todays boxes.
