And oh, I like the new iChat theatre feature too. No not the philandering background feature (hehe). Rather the one that allows you to show your presentation. That would be great for "distant teaching" (tm). Or doing remote presentations for that matter. You can also use it ala VNC (screen sharing), and remotely control another mac while perhaps guiding the other person on the other end of the conversation.
Another shiny tool in making the world flat!
