Instructions for application were in the roadmap post, however it was targetted at modders (Those creating content). https://www.studio-397.com/2017/02/roadmap-update-february-2017/
Correct, at this point we are looking for modders as we want to help them prepare for DX11, but not yet for people to test VR (we're still implementing that).
Happy to test too ( oculus cv1 ) I log many hours sim racing pc time ( & VR only ) Ps my whole setup is for sim racing in VR only I don't use any other type of titles or monitors
