Come to think of it, is it possible to create tutorials like the basic ones that Alice already has? Is it java script, or something similar?
Also if it is Java script, perhaps you might consider creating an editor for creation of such tutorials for general use? I'm sure teachers would find this a great boon. And if you find that students are using it to cheat, just treat it like the answers to the exercises and require a password for access. That way the teachers can't complain.
Just a thought...
