Collaborating around the world

Now that the world is so very small in lots of ways, where people can join together on projects from all corners of the globe, I can see that google docs would be invaluable as a tool for helping that collaboration. It's easy to use, so I could see myself using it if a situation like that arose. In my personal life.... I'm not so sure. I probably don't use the Internet enough at home for it to be useful. But I'll have to think about that a little. I'm sure there are possibilites that haven't even occurred to me as yet.
