I would say no, at least not in VWRAP. Virtual World Region Agent Protocol bundles all of the cross-domain trust issues, protocol negotiation, and service establishment into a neat package that hands the viewer a blob of protocol-specific information on how to start communicating with a region. We have multiple groups involved that have looked at a fairly diverse set of use cases and are moving toward rough consensus and working code. In contrast, I can't see the standardization of a client<->server virtual world scene graph protocol becoming anything other than a rubber stamp of the current Linden Lab implementation ported to HTTP or a wandering discussion that is a few years ahead of its time.
