Whiteboard and sharing application:

My question is if exist some project or there is already an application or solution for the sharing application or whiteboard, with other name for Asterisk. For example: I want to make a conference and the lecturer can share and application to the others participants like a PPT or a picture, of course in this case everything is over IP. There is anything on Asterisk’s world to do something like that???

I want to ask too, if exist any kind of Web-Conference, or something like this???

Not sure if this is more or less what you are looking for. But… You may want to check out dimdim.com. I haven’t touched it since previewing it when it first came out, but I’m going to guess it is close to what you are trying to accomplish.

This is exactly what I want.
Thank a lot.
