Audio ConferencingEdit

Skype allows you to audio conference up to 8 people when running a dual core machine. You can also audio conference up to 100 people using SkypeCasts. This is a beta service and can be a big quirky. Skypecasts are open to the public while free, but you can mute everyone and selectively unmute listeners to participate in the conversation.

I would also suggest looking into web streaming software such as ShoutCast server (runs on Linux) that allows you to stream conversations out onto the Internet --- basically a radio broadcast. You can learn more about this type of technology at www.webcastacademy.net.

This type of audio broadcasting, with a chat room and WebHuddle in the backgroud, and allows for much of what you would use in a traditional WebEx scenario. Albiet a bit more complex.
