Free Web Meeting Environments?

doval asks: "I just took a look at Webex and Centranow. For those of you who have seen these sites, is there an open source equivalent? For those of you who have not, they offer the following (currently wintel only): Presentation Sharing, Document Sharing, Application Sharing, Web Co-browsing, File Transfer, Desktop Sharing, Telephony Integration, Internet Voice, and Video Integration. Think MS Meeting, ICQ, PC-to-phone, and PC-to-PC all in a browser (synchronous). I am familiar with open source bits and pieces like OpenH323, Jabber, plus collaboration environments like Zope. However, I do not know of anything like the sites I mentioned. Particularly, I would like to get my hands on a good example of Web synchronous application sharing and PC-to-phone."

VNC

VNC is a great application for viewing another person's screen. Free, cross-platfom, and useful. Just run the server on the machine that needs to be seen, and people can connect using any java enabled browser. I think it is GPL, so it could be integrated with existing GPL code.

For Unix machines, the server keeps a virtual desktop that everyone else could connect to an view/modify.

They even have a Palm Pilot VNC viewer app.

PC-Phone

I am also really interested in finding a free PC-phone product that supports linux. This is the only thing that makes me reboot when I want to talk to my girlfriend when she is away at school.

This may be what you want
