OpenSimulator is an open source virtual world platform that supports Second Life assets such as objects and scripts. The codebase fuels a number of alternative distributions such as RealXtend and Openlife Grid. Although the platform is only in Alpha, a number of public grids are already online.
I urge anyone who cares about an established Second Life identity to register it on existing public grids. Although your Second Life identity may eventually cross seamlessly between SL and Opensimulator grids, the reported working prototype is only a first step down a long road which may never be completed. Registration is free, so you might as well head off claim jumpers.
I took the additional step this weekend of installing a few of the server and client versions, partially cloning my luscious avatar form (following a Plurk comment from Dandellion Kimban) and stepping into the public Openlife Grid. I'll provide more detail on the process in a future post. If you have any questions that can't wait, feel free to leave them in the comments section.
My fellow Avatarians, the time for emancipation is now. The gated walls of Second Life can no longer contain us. I have tasted the freedom of a foreign Sim and it is sweet...even in semi-Ruthed form.
