This plugin would be useful for online conferences. Will people have the ability to share their screen for presentations?
that would be cool and useful too.
so I guess they don't have this feature then?
It is possible through the use of software that captures the screen and emulates a webcam. In AVChat it shows as a webcam option and the video stream contains your desktop.
Here's an older article I wrote on the subject in relation to AVChat http://avchat.net/blog/screen-sharing-in-flash-video-chat-applications/
