I have tested two "Dexxa" webcams (compatible with Logitec Quickcam 
Express), on the same USB bus. I set it up to take alternating snap 
shots from each camera. This works well and could be expanded to more 

However the limitation was the USB cabling. With hubs and extension 
cables and hubs, things start getting unreliable after about 15m.

Have fun and let me know what you learn!
