This might be stupid, bu is it possible for you to make the software capture component of OBS a standalone virtual camera application to be used with other programs? I personally think it's robust enough, even moreso than other existing programs out there. What purpose would this have? Well, say I want to switch from my webcam in a Google Hangout to my screen, or a specific window on my screen, I can have this app running, select my monitor or specific window and then in the Hangout, switch my device to the software capture. I think this could be useful to some people like myself, since OBS doesn't handshake with Livestream. Or i could just use Ustream instead since you said OBS works with their service.
Also, thank you for implementing a start stream hotkey option into OBS. Glad to say I can assign the same shortcut to both start and stop and it works a treat.
