The advantage Unisfair touts over Second Life is that its environments are closed and secure -- no chance of people flying through the presentation or creating a scene in animal mascot costumes during the pie chart slideshow. According to GigaOM, Unisfair claims to have grown 350 percent in 2007. The company was founded back in 2002, however, and seems to have hit it big after specifying virtual meetings and the "software as service" business model. Among its customers now are Cisco Systems, National Instruments and business intelligence firm Cognos.
