Thanks for the advice about the command line parameters too. I'll have to use that. Only problem is that the adapter IDs seem to move around all the time, connecting and disconnecting the Rift. Sometimes it'll be adapter #1, at other times it'll be #3. Ah, Windows.
This is amazing. Even in such an early state, I can see how seeing an avatar in the mirror can really increase the sense of presence. I really just wanted to pick up my arms and see my fingers move and all that. But it's a great start.
