As a teacher who uses versioned TeX for all of my artifacts, this isn’t the panacea you hope for. Many of my documents will only compile on my machine because I a have a bunch of dependencies scattered about. There are also many types of artifact that require an order of magnitude more work to produce in TeX compared to something like OmniGraffle or PowerPoint. Even if you could somehow overcome the technical hurdles, you’d run into the problem of teaching materials not possessing even a partial order. Even if you somehow get teachers to agree on a lattice or total order for teaching artifacts, you’d need to deal with the idea that producing teaching materials is a way for the teacher to synthesize the content they are about to teach. Often the artifact is something of a byproduct of the process of the teacher making sense of the rhetorical situation the are about to undertake. If you just snag the highest rated artifact, that process doesn’t happen.
