We’ve been talking about Linden Lab’s plan to open-source the Second Life client. They did that on Friday, according to an article in the Second Life Insider–or, at least, a couple of pieces of it. Who knows what it portends? But, just as the open-sourcing of the client software came sooner than anyone expected, this initial trickle is sooner as well. Perhaps the server stuff will get completely opened up soon. If it does, expect another explosion in SL usage. I’ll be interested to see how much, if any, attempt is made to hook all the little independent SLs together. If it happens, it could truly be the start of something resembling the 3D Internet.
