Trying to ride the Wave...Google style

So today I got the Google Wave invitation. I'm playing around with it now and for classroom uses, I see two issues so far. First - because it is still in limited release, getiing a whole classroom of people to independently to get the wave is a logistical challenge. Second - many schools are Microsoft IE, there needs to be a Google Chrome install that would have to be on every computer in the lab. Obviously the second point is negated if they have a project to work on at home. But that would bring up the second problem of home internet access. There does seem to be a learning curve as well. My first two uses will be for students to create their own tests (yes there is explaining here that will be done later) and to have real time note taking. I'll update more as I figure (and configure for HS classes) the Wave.
