“Second Life is a 3-D virtual world entirely built and owned by its residents.”, says its Web site. With more than 2 million virtual citizens online, it is a surprise hit, and it seems there are more tricks in the sleeves of Linden Lab, creator of Second Life.

Vivox had announced last year that it will be providing voice communication to Illusion Factory‘s island in the Second Life world. Citizens of Second Life who would reside in the IF island will be able to call other Second Life citizens using an ordinary phone or via VoIP.

And now, Star Trek in Second Life? In the latest Consumer Electronics Show in Las Vegas, CBS CEO Leslie Moonves keynoted day two of the show, and here he announced CBS’ collaboration with Second Life, using Star Trek as an example. Whether how the Star Trek material is going to be used in Second Life is still anyone’s guess. Download the keynote here (in PDF).

But imagine being a starship captain in Second Life! Or a Ferengi. Or maybe an actor playing a starring role in a Star Trek series.

BTW, LindenLab has released the Second Life Viewer code, making it open source.
