Well Google Docs still is less irritating than screensharing what you are doing in Google Docs via Skype.

I'll give you that :)

I can see it being extremely useful for group projects in university settings...

Pair programming is okay with two people looking at one screen, but once you have more than two people, it really is just a drag. Of course, you can use git and contribute separately. But looking at the same version of the code seems tremendously useful.

When I was at university doing programming, we just sat three people to a machine.
