3DXplorer from Altadyn, is a Java-based online meeting space where companies can fully customize the virtual environment and hold meetings similar to the ones they would have in Second Life.
"It's Web-enabled," says Natalie Wood, assistant director for the Center of Consumer Research at Philadelphia's St. Joseph's University. "You don't need a fancy computer, and you don't have many firewall problems. And you do not need to be highly competent to use 3DXplorer. Second Life definitely has a steep learning curve."
