Central Desktop is much more than a web meeting tool and provides facilities for team collaboration, document sharing, discussion forum, wiki-style editing, and project status tracking. They offer a generous 15 day unlimited trial of the program, and proudly display the Business Week "Best of the Web" seal on their website.
All these facilities and more can be obtained for $99 per month for the Workgroup edition, which is recommended for small companies and departments. They do also offer an Enterprise edition for medium to large sized companies, but they do not state the pricing structure for that edition on their website.
The tool requires the usage of Java Runtime v1.1 or higher to launch a web meeting. Finally, the tool also offers instant messaging that can be integrated with ICQ, Skype, AIM, Yahoo, MSN, and Jabber.
