I was at one of the monthly eLearning meetings a couple of weeks ago and one of the attendees was demonstrating Google Wave for the group.
It is an interesting mashup of a chat, wicki, virtual workspace and information repository. Apparantly, you can start a "wave" and invite others to it. Once people have access, they can collaborate on a group project by typing information into the wave workspace, dragging images, videos and other files directly into the workspace, search, edit other's work or comment on it. Throughout, you have the ability to chat in real time with other people in your group (those with access to the wave) about the contents being added, future directions, whatever.
If you can't participate when others are working, you can visit the wave at any time you wish and hit the "playback" button which will play the wave as it progressed, including changes, chats, additions and deletions.
eLearning was thinking that it had the potential to replace Moodle as a class management system some time in the future. However, in its current incarnation, it wouldn't work since it isn't really possible to integrate the platform with the school's class management system and it isn't possible to keep student information private should they or you wish to do so. It does look like it has real potential to be a useful collaboration tool.
At this point, it appears you can only play around with Google Wave if you know someone who has access and they extend an invitation to you to join. I don't know what criteria Google is using to decide who initially gets access. Potential developers probably. Anyhow, someone in the eLearning group now has access and offered to invite me. It was an invitation I gladly accepted (I LOVE playing around with new technologies).
He said it would take a couple of days before I received the confirmation email from Google granting me access.
I would be happy to extend the same invitation to my LJ friends if I have the ability to do so and if you are interested.
I have to admit that it has crossed my mind that this whole "by invitation only" aspect of the project might be a really clever marketing/propaganda ploy.
