@anandpv : Unfortunately, I absolutely need global shutter. But I'm curious about your comment on RP - it's 1 GHz, 512 MB RAM. Shouldn't it be able to record a 100 FPS VGA video (my calculations say the datarate from camera will be 32 Mbps or 4 MBPS).
@andre_teprom : Oh yes, that's my first choice. Unfortunately it's turning out to be hard to get this in Asia (India). You would think it should be available in plenty since Google's using it, but that logic of mine has failed.
