This is an outstanding product. I can easily see it letting non-technical teachers have their own Kahn Academy. Any plans to let teachers share or sell lessons/lectures with one another? I experienced some bugginess submitting forms with the unit name clearing my entry. Is it possible to embed videos on external sites? Only thing I dislike is how dull and drab the sample lesson is. I'd actually use it to teach (or re-teach) some concept that the audience is likely to remember. Fantastic job.
