Question by todundmaiden: How can we do multi-site, international video conferencing? Any software or paid service we can use?
We are having a high school reunion in October in China. Some people from different countries can not go. We are thinking of having a video conference with the reunion party, but don't know how. Could you please help?

You could look at Tokbox (used to work there).

A couple of things to keep in mind:
The chat performance will be directly affected by both the internet connection quality of the participants & the distance the video has to travel. As such, you might have some issues with latency/delay with any video chat service.
