I don't think that's what she's talking about.
I don't think it's possible simply because there is a fundamental flaw to the medium. Theoretically, events such as Burning Man are perpetuated through a lens - as in the performances are transitory but the representation of these performances persist through the perspective of the attendees either through a photographic or videographic lens. There is separation between those lenses and the performers that is typically filled by other attendees, the natural setting, or even other performances in the periphery. In a virtual space, the lens is explicitly the domain of the performer instead of the audience and there is, consequently no separation. Furthermore, there is the issue of the inherent permanence of everything that exists on the internet; even assuming a recording of the event is saved by the virtual attendee, thus becoming the property (not in the legal sense) of his or her perspective, and promptly deleted from the performers space, the recoding continues to exist in near perpetuity in some form devoid of any additional lens space.
