If you’re thinking about trying out virtual, immersive environments for your business meetings or training sessions, but find Second Life and OpenSim too difficult, and ProtoSphere andTeleplace too expensive, you might want to take a look at some business-focused, browser-based virtual worlds.
The idea is that you send someone a link, they click on it, and, maybe after downloading a plugin, they’re in the world, ready for your meeting. No software to install, no complex interfaces to learn.
Don’t expect to see the same breadth of features as you do in a full, standalone world, however. In fact, calling it a “world” would be a misnomer, since there’s no world in there, as such — just your meeting room.
