Live screencasting for both PC and Mac

Question

This is not exactly very programming- but we are hosting a code hacking section every week. Now we have a guy left our origin and working oversea, but he still would like to join our event :) So the question is how can we do a live screencast from our Mac to him? The constraints are as follows:

1. It has to be live- not pre recorded. An option to both record the screen + live broadcast would be great.
2. Ideally have Linux + PC + Mac support
3. We are behind an uncontrollable NAT (we usually meet at public cafe) so probably a screencast server is required. Alternatively maybe a pull connection? (The other guy in the foreign place might have more control to the network)

We tried DimDim (www.dimdim.com) and for some reason it just fail to work properly- too many glitches, somebody either couldn't join or screencast is not visible.

VNC is built more for remote desktop than for doing a presentation, but it should work pretty well. The protocol is open, so there are many free clients and servers for Windows, Mac, and Linux. Here's an example setup for presentations. Here are some clients/servers you could use:

• http://www.tightvnc.com/
• http://www.realvnc.com/
• http://www.uvnc.com/
• http://www.testplant.com/products/vine_viewer (OSX)
• http://www.karlrunge.com/x11vnc/ (Linux)

You can also record a VNC session using something like vnc2swf.

I'm not sure about the NAT issue though, VNC probably needs to have ports forwarded to work. I'd give it a try normally first, they try to do a reverse VNC session.

Skype supports screen-casting. I'm not sure if it works for a conference though depending on bandwidth restraints. You need to use the latest versions though, it only has recently been released with these features. -- http://www.skype.com/

A free choice might be Vyew, which should also work. Works via a web interface. I have never used this before, but it looks like it fits your needs. -- vyew.com/site/
