Stumbled over the following technologies:

SharePoint: An html console to hold a bunch of stuff. If people bothered to enter the metadata, the tool would be very powerful. You can view a web page that organizes files in a variety of locations by virtue of their properties, not their location.

Class Server: A way to help teachers automate the paperwork so they can save time for real teaching. Would be very interesting to have a peer to peer network for teacher-authored materials. Perhaps also a credit system so that creators of more popular materials can get paid. TiVo-like subscriptions so you can receive materials that intersect with your interests automatically.
