Safari — iGlasses

I know not many of you have iGlasses, but for those of you that do (or for those of you that may know), why or what does Safari use the iSight cameras for? I know it has Quicktime built-in, but that’s for playback, not Pro’s recording, is it? Post any answers in the comments, I’ll appreciate any knowledge you can give me. For those of you that this is your first hint to any of this, now you know it’s live-video-from-local-camera ability is there somewhere, somehow.
