How to get stereo webcam as Object texture?

Hello, In my current project I use Oculus Rift DK1 and want to add a virutal screen in my VR Demo that shows the "real world", getting input from external webcams. I just figured out how to assign a webcam image as a texture to Gameobjects. So: Input from 1 webcam to 1 object. My question: is it possible to apply the feed of 2 webcams as 1 stereoscopic image as a texture to an Object? Can anybody help me?
