How many Webcams can be captured simultaneously?

Hi,

for a new project I need to capture 80 (!) Webcams simultaneously. Not a video, just one single picture of each Webcam at the same time.

If I have enough (active) hubs to connect all those webcams to my Mac, can the mac handle that many cams? (Resolution ~10 MegaPixels)

I know how to capture a Webcam via QuickTimeSDK, so that's no problem... but 80..?! Is that possible?
Or would I need to split the cams over 3 or 4 Macs and synchronize them?

Aya~
