And then, possibily a way to mix them and stream it?

I don't know if you can out of the box, but one possibility is to send the stream to a virtual video device first, which can then be encoded from a LiveDeviceSource.

Just with a quick google, http://www.soundmorning.com seems to have a piece of software called VirtualCamera that may do this for you. I have not used this particular software, but have done something very similar with an Axis Network Camera to Virtual Webcam driver.
