Live Video from multiple cameras

It appears to me that the video library in processing currently only supports reading a stream from one camera. Am I correct or does anyone know of a way to read from multiple cameras within the processing environment?
Thanks!

from what I understand that is correct... however, I have been thinking of ways to get around this, and in a computationally "cheap" way.
one solution could be using a video mixer. just feed the two streams into the mixer, divide the screen with a transition, leave it at 50% and then just send that to processing... then tell your proggie what side of the videopixels are what 'feed'
similar method, but with another type of hardware: get one of those surveillance video splitters (they have a name, i just cant remember what they are called). you can get four or more feeds in there (depending on the hardware), and they are split four (or more) ways across the screen. you can probably get one of those used for less than 200 bucks if its in color, even less for b&w.
in any case, doing it like this is probably much faster than having two video feeds clogging up your computer's data bus.
btw: i love reactive. my work/interest is similar than yours, and i think we may even have a common friend from itp, andres jimenez.
hope this helps

Thanks for the response! Indeed, sometimes the best solution is a hardware one. . . . .
Best,
