I have an Oculus CV1 that I have no idea how to use without Windows. So I'm definitely interested in the frame as well. However I suspect it's going to be fairly expensive.
My Valve controller still works fine, although the new one would certainly be a nice upgrade (I don't use controllers much).
If you don't have a compose key, well, you should have one. You can define it easily in the Kde control center. I suppose there's the equivalent in Gnome.
Oooh, I know that one!
What's UP highway?
