Web.alive is the platform to beat since it's backed by a large, well-known networking technology firm and offering a broad range of business-friendly features. These include the ability to put up screens inside the 3D world and to share desktops, PowerPoint presentations, Web pages, and other content. Web.alive can be integrated with corporate directories, and can also be run completely behind a company's firewall for maximum security.
Companies can create and upload their own virtual environments, or choose from a selection of pre-built meeting and conference spaces. And even the pre-built environments can be customized, says Web.alive director Nic Sauriol.
