I'm not too familiar with the ins & outs of such sensors, but what determines the limit ? Being MEMS based, you could have quite a bit of freedom w.r.t. dimensioning structures I assume.

That's beyond me as well. It sure might be nice from a technical point of view, but whether it brings real benefits these days I couldn't tell.However, I don't know if it's practical to use them to feedback compensate midrange or tweeter speakers.
I wonder if anyone is working on a MEMS based microphone?
MEMS microphones
The MEMS (MicroElectrical-Mechanical System) microphone is also called a microphone chip or silicon microphone. The pressure-sensitive diaphragm is etched directly into a silicon chip by MEMS techniques, and is usually accompanied with integrated preamplifier. Most MEMS microphones are variants of the condenser microphone design. Often MEMS mics have built in analog-to-digital converter (ADC) circuits on the same CMOS chip making the chip a digital microphone and so more readily integrated with modern digital products. Major manufacturers producing MEMS silicon microphones are Akustica (AKU200x), Infineon (SMM310 product), Knowles Electronics, Memstech (MSMx)and Sonion MEMS.
