Get your Own TV Channel
I've always been fascinated by broadcasting. That's why I use blogs a lot, but there's still video broadcasting. How about your own TV show. You can use it as entertainment to draw attention to your site or broadcast company meetings and presentations.
Livestream
It's an interesting platform. I'm a fan of satellite radio and one of the hosts has his own show that he also broadcasts from home. He built a $20k studio from his home, but you don't need to do the same. The software Livestream provides does all of the heavy lifting and as long as you aren't planning on taking calls or needing sound or video effects, you can make what they provide work. It's definitely worth a look. Who knows when you might need a solution like this. The paid versions are a little expensive, but they have a free version if you don't mind a little advertising on the page.

UStream
This site allows free, live streaming video along with an accompanying chatroom. This provides a good feedback solution for conducting business or running your own celebrity room. There's even some mobile solutions if you want to watch or even record video to publish from your phone.
