I can last hit OK with a trackball (after some getting used to, thanks to RSI), but edge scrolling is difficult.
With two trackballs, perhaps one of the wheels can be used for moving the screen, and the other for moving the mouse.
They've implemented a "chat-wheel" with common in-game phrases to help with communications as well, which seems to be a perfect fit for controller play.
I just can't wait for the day where I can invite people over, buy an 80" TV, and play Dota 2 split screened on controllers!
