In short, iChat Theater is a new feature that will allow the broadcast of, and collaboration on, just about anything we do on our Mac. Of course, a developer will have to design their app specifically to incorporate these new features (hint: submitting feedback and feature requests is a good thing), but just consider the possibilities: instead of having to jam pack all your tech support calls into that once-or-twice-a-year family holiday trip, you can fire up Leopard's iChat and show mom and dad how to make a slideshow in iPhoto over the web, with both video and audio of yourself and iPhoto. Now expand a little: is your job on the verge of granting you telecommuting privileges? Or perhaps you're a teacher or a technology scout for an educational organization? This new Leopard feature opens doors much larger than the one for mom and pop; with iChat Theater, teachers and businessmen alike will be able to work their magic in entirely new ways, and not just with the tools Apple provides. The beauty of iChat Theater is that it's an open platform, so to speak; want to brainstorm in OmniGraffle with a colleague on the opposite side of the country? Need to teach a last-minute digital art class in Lineform for a friend halfway across the world? No sweat. Although I have no idea whether The Omni Group or Freeverse have already hopped on the iChat Theater bandwagon, plenty of comments and requests from their users could probably ensure they do.
iChat Theater is gonna be a big'un boys and girls, and I already have a couple handfuls of reasons as to why I can wait for Apple to take their time and (hopefully) get it right.
