How fast are you engraving?

Right now my steps are limited to 37kHz and with 8x microstepping that limits me to 470mm/s (or F28200). My acceleration is 7500mm/s/s which means it takes about 15mm to get up to full speed. I haven't really tuned the acceleration and I suspect it could go much higher.
In order to engrave faster I would have to reduce the microstepping on X. Dropping to 4x would still have 1mil resolution and I could reach 940mm/s, which is about half of what something like an Epilog claims to be capable of (I saw suggestions that low end models could hit 75 IPS, or about 2000mm/s).
So my question is: How fast are people driving their 2.x laser carriage? Has anyone hit 1000mm/s or even 2000mm/s using DSP/Retina type solutions (or a smoothstepper)? Is it practical for the makerslide carriage? Most commercial engravers really minimize the size and weight of the final mirrors.
