Moving the knowledge from one machine to another via learning rather than trying to copy in some form or another seems like a good approach. You don't limit the architecture of the learning or teaching implementations. It even works if the learner is a human, which is a bit different architecture :) I also like the idea of having teaching output parsable by humans. Then you could ask your teacher AI, teach me (show me) what you know.
