A note to add:
From the information I gathered, so far, I feel the concern surrounds the movement of OpenAjax from a traditional web based technology to a virtual world technology such that it must ensure the rights and protections of asset ownership through its exchange. The owners of the assets include those that would never be directly involved in the OpenAjax membership, as they are the numerous content creators of the virtual worlds that would never be exposed to such OpenAjax membership or layer.
The layer that already exists provides an indirect ability to use Ajax technology. There is also those already interested to take the technology to a more direct approach with virtual world interoperability. I can only speak of details from a perspective of Ajax and software that I've authored, but I already can tell the virtual world interoperability requires further thought into Ajax or an evolution of such software to a new model.
I'm anxious to see this happen.
