Well, I wish I could tell you what would work. It's strange, but our university opts for commercial apps every single time.

We use a tool (which might sound familiar) called WebCT, which is commercial - it provides notes & discussion boards for every subject a student takes. Actually though, the lecturers have to use it for the students to get any benefit, and many don't! It's a shame, and so I cannot imagine most lecturers taking their time to master your system (however appealing it might be).

It's amazing, we even use Outlook Exchange servers, when there are so many other excellent O/S alternatives.

In a way, it seems that the bureaucracies prefer commercial stuff.

So my bit of pessimism is that it will take a lot of arm twisting to get people to use educational software :(. What a bummer.

However, it sounds very interesting, so you should please push forward! Good luck!
