>What if the doctors were all linked in a group through Facebook
Fortunately, other professions hold privacy in high enough regard not to sell their clients' information to the highest bidder. And this is precisely why this announcement is so disappointin; this scenario explicitly will not happen via the Oculus product. It will require yet another round of innovation in the VR space because no doctor worth their salt would use a facebook product with their patients' privacy at stake.
The patient is a mother experiencing pregnancy complications, stuck a remote area of Alaska, in an Oculus conference with a doctor in Seattle. Her doctor diagnoses her and uses the network to find a specialist in the specific condition. Turns out there's one in Portugal, and at an appropriate time the Portuguese doctor joins the Oculus conference. The two doctors work together to make a recommendation for the patient. Like a videoconference that actually feels like a meeting (a holy grail for decades)
This is the kind of application that would be best pursued by an independent company, but is certainly more likely from Facebook than from Valve.
