eConference is a network-aware Rich Client Application created for enabling ad-hoc workgroups to collaborate.
In particular, eConference is a text-conferencing tool that supports synchronous, structured communication. eConference is designed to accommodate the needs of a workshop without becoming an unconstrained, on-line chat discussion.
The tool is based on the XMPP protocol, an IETF standard for instant messaging and presence awareness. You can setup your own XMPP server installation within your company intranet, or exploit the free network of XMPP servers federation. As of ver. 4, eConference also supports audio communication via Skype.
