Kaman Vortex and Doppler Shift MAF sensors are not actually MAF 
sensors in that they only measure airflow volume, therefore you will 
need temperature and pressure (altitude) compensation which gets 
messy.  The Thermal Mass Flow meters (Hotwires) are true mass flow 
devices requiring no compensation.  But anyway, if you want to go this 
route, take a look at Laser Doppler Velocimetry.

This idea appears to be somewhat similar to the Karman Vortex MAF sensor
used on some Mitsubishi vehicles (e.g., Dodge Colt)...  

Time for more coffee...
