Yes, but this server application was only introduced with the DK2 and the 0.4.x SDK which was delivered after the facebook acquisition. Whether they would have hold back the source code without facebook - who the hell knows?
Huh, I didn't know that. I never really had a look at any SDK earlier than that. I just had a false memory that the DK2 came out before the fb acquisition. I do remember Oculus intimating that they couldn't open up the tracking code because it was some proprietary stuff they'd bought but that's almost certainly not the case now.
After Facebook: Closed Source, Windows-only.
