Matt and I have used Google Talk in video mode and I was surprised at the quality. I have Google Voice but haven't really use it. The phone number I got was 2 area codes away from me. when they get the rights to more spreads of phone numbers, I'll probably use it more. While I have Skype accounts, I haven't really used them since discovering that the Google Talk Plugin works. The Google Talk Plugin wasn't always useful, well, for voice maybe, but, not with video.
Unfortunately, I can't just discard Skype, just like I can't totally dump Windows, clients are used to Skype, and GoToMeeting is a Windows only app.
What we need to do is start experimenting with Ekiga, and see if we can contribute to that project. I see Ekiga (from which GoToMeeting came) as the present day Open Source version of Skype, that is, until Google opens up Talk and Voice to the world.
Edit: Marc had a great idea, we can experiment and see what works between us. We should try and set something up. I'm most interested in seeing if Ekiga can do a video conference.
