Video in the Classroom

I'm trying to pull some ideas together about what to do with my 4th and 5th year computer classes. Right now, we're tackling PowerPoint, blogs, and Flash projects, but I'm trying to work the curriculum towards multimedia projects. I want to get the hardware to incorporate video and sound files into their work easily. I'd like to see the kids directing their own projects and really provide them with the resouces necessary to take off wtih their ideas. I'll have to check whether I can serve files from my computer on the network and by doing so make stuff available for the web. We'll need quick access to pictures, movies, and audio clips for our projects.
