1. I have heard, tests show, IMAQ-functions have the perfomance problems comparing to OpenCV (from 1.5 up to 10 times) 
2. It seems to me we need:  
	a) a several base functions that solve low level incompatibility problem OpenCV-LabVIEW 
	b) dll-s  of OpenCV functions 
	c) a short manual that explanes how to wrap new OpenCV function 
So, everybody can wrap the functions in need. Obiously, for a lot of simple projects that assume mass yielding it can be the best way to go. 
Best wishes,
