I’m not that familiar with the iPods; do they have any recording ability? If not, you might want to add some portable digital audio recorders for each classroom too; something really simple that students could easily take with them. I think video and audio are good for different projects.

I don’t know if it’s exactly right for the wishlist, but maybe something about control over what is blocked. The ability for a teacher to unblock a specific YouTube video for class, for example, without unblocking the whole site, would be useful.

As a former music & band teacher, I’d also add digital keyboards to your list. I actually haven’t kept up with the music technology so much in the last few years, so ask your music teachers what their dream would be. I’m sure your art teachers would like Adobe CS3 available for their students too.
