From what I can tell it is all done by the application and these are relatively new, I tried searching for ways to remove the Facebook integration but all of the results where for Facebook being bad in general. I don't use the service at all.
The main reason I want these is for the cameras and maybe the audio playback capabilities. The stereo picture and video capture capabilities of these are very interesting to me. I currently have a pair of Ray-Ban Wayfarer sunglasses that are really nice. This is one of those products where I would want to know for a fact that I can remove the spyware from it before I get it. Even if I only take pictures of boring things like architecture and landscapes, I don't want Facebook to have those pictures because they have a long history of abusing such information.
