To facilitate more informal discussion, I've created a group in Second Life called the 'Interoperability Alliance'. The group has open enrollment and the notices are open to anyone. My intention is to pass ownership to members such as Peter Haggar or whomever the alliance deems appropriate. I just wanted to get the discussion going, and forming an in-world group seemed the most appropriate.
I also started the 'Virtual World Interoperability' group as well, which is the same as the 'Interoperability Alliance' group, but with closed enrollment. I figured perhaps the Alliance would need a more restrictive group for controlled discussions, but will defer the group on the best way to proceed.
Look forward to the evolution…revolution? :)
