Yon, the idea might not be yours, but it was the first time I saw it, and boy, I think it's an _excellent_ idea. OpenACS would be appealing to users looking for a solution, and still have the power to be whatever you want it to be.
I love this. If you add "Education Solution" (from the ACES folks), OpenACS could become a great thing for schools/colleges/universities to addopt. Having it out of the box would be fantastic!
We need to finish this port faster so we can get these nifty ideas to work. But if someone would grab this and start implementing now so we could release it with the 4.x release, that'd be much better!
