I was wondering if the VorpX framework would support input in the HUD from two cameras (one per eye). The cameras would just be 2 USB webcams to the computer. I would love to attach two cameras to the Rift and have a small 3d view in the lower corner to pull up on demand (to see outside the rift). I know you only briefly touched on having a standard HUD view in your drivers, but a little addition like this would justify paying a premium for your drivers to many I assume.
