alt Hacker NewsGiven Valve's past history in this regard I'm inclined to believe it'll be possible to install whatever you like on the thing, and that there'll be a reasonably well documented way of integrating with the sensors/display. Valve have got decades of form on being as open as possible with their hardware and I've seen nothing recently to make me think that's changed.
Software wise their SteamVR / OpenVR stuff is very closed source. Someone had to reverse engineer their Lighthouse tracking which is hard but doing that is easier than making 6dof SLAM tracking just from camera access. All I am saying is its not easy and people will have to do hard work.
