“Project Skylight” is its name apparently, and it’s the project that will hopefully deliver Second Life in a web browser. Tateru Nino got a confirmation from Linden Lab that testing will be occurring, so hopefully we’ll see some concrete examples in the short-term.
It’s a well overdue development, and one that is not so much innovative as essential for Second Life’s longer term survival. I know that for me my time in SL use will increase with a browser based version, as I can do it alongside my other browser activities. It’s a no-brainer really and kudos to the developers making it a reality.
