OP here! I've been keeping a very close eye on the SimulaVR project for a while. I agree with most of what you've got here, and would love to be able to try it out in the future.

One question I've got about the window management system - I make heavy use of virtual desktops so I can swap several windows out simultaneously (all my source code on one screen, my database GUIs on another, etc.). I'd run out of room using a spatially tiled VR interface unless I had "sets" or other groups of windows (or different vantage points); how is that being approached? Is there a "virtual desktop" equivalent?

Any chance of coopting other hardware as part of your development/deployment strategy? (Vive Focus 3, maybe?)

I'll definitely continue to watch the project - please let me know if I can ever be of service in the endeavor. You guys are building an awesome future.
