It's marginal... I've had occasinal good luck with a single webcam
but it's not stable enough for production use. I've had lockups,
kernel oopses, and just partial frames.
Much of it depends on your webcam and the driver it uses. There
isn't any clear answer, unfortunately. You will have to
experiment. But for stability, I'd get a hardware framegrabber
and/or a board with a faster CPU.
I now use an IP cam; works like a charm and plugs into the ethernet
port.
