I was able to play with it a little bit but I'm hitting some technical issues now. The camera reset seemed to be moving my head a bit odd. Resetting with my position far to the left and up of the default, caused my head to clip out of the room. Unfortunately, I'm only able to start up to a black screen now. Wish I could poke around more, the virtual desktop idea seems pretty cool.
I'll back you up on not wanting to use the 'r' key thou. From my personal set up, I assume most people are resetting so they are far away from the keyboard to avoid interference with their monitors and the leap. A larger or more obvious key is a bit easier to hunt down.
