Hubz Instant Messaging Server

From Digi-Net Technologies, Inc.:

Hubz is the Internets first truly web-based instant messaging solution. The Hubz technology turns every web page on your web site into a Web-based "walkie-talkie" (allowing users to see all other users who are sharing a page with them, and send them instant messages). Hubz dramatically expands the functionality of the Web by allowing real-time, two-way communication between your web surfers without special plug-ins or client-side software.
Hubz will increase the "stickiness" of your web site, filling a vital role as a very powerful community-building tool. Hubz will fundamentally change the nature of your visitor's web experience. Currently Web pages are simply a medium to display largely static information that one may wish to make available on a server. With Hubz, every Web page is now a destination; dynamic, alive and filled with other people with similar interests.
