Interesting. Something similar to this was my diploma thesis, although I wasn't able to find this as prior art. My intentions were mostly to have text adjust itself beforehand to the reader's preferences and pre-existing knowledge. Then certain parts would either be abridged, or fleshed out in more detail; explanations added for concepts not yet known, or further sections pertaining to additional interests. I thought this to be perhaps a good way of writing things to teach with, in that the result would be applicable to a wider variety of readers. However, writing would likely be a problem, since (a) much more content has to be written, and (b) everything should make sense in all possible combinations of snippets, which can be hard to guarantee.
