WorldWide Telescope for HoloLens

Clearly, we need to use HoloLens with WWT. I know Jonathan Fay, Curtis Wong and others (e.g. me) have talked about this for quite some time, but I'm hoping we can use this forum as a way to figure out which functionality to implement first. Let's discuss! (And, Jonathan, is the 3D imagery in the demo app shipping with HoloLens directly from WWT?)
