The initial sign-up deals don't seem to be too bad if you just want to try it (e.g., $50 for three months).
That being said, you only get two lectures a month for that price. It doesn't even sound like you can get archived material for free (maybe I'm wrong).
Here is my guess about what it will look like. There will be a brief introduction, and then the lecturer will play in a tournament to demonstrate the concepts introduced. Given that the tourneys are "closed in order to prevent collusion", the other players may be patsies that play precisely in a way to make the point of the lecture. Regardless, I doubt the opponents and conditions will be similar to what most low limit tournament players will face.
During the lecture, the questions will be relatively silly ones like "Why did you raise XX from that spot? I thought Sklansky said..." OK, maybe they won't say the last bit, but they will be thinking it. Anyway, the answer will always be something along the lines of "It depends on the situation." Anyway, in order to teach well, this school will need to teach the abstract concepts and give enough examples to show how these abstract concepts can be applied dynamically -- that is, not ABC poker. I doubt that they will do this (correct me if I am wrong).
FWIW, I think HoH does this relatively well. He qualifies almost every statement (e.g., "usually this is best, but sometimes..."), and then uses the copious examples to show how the concepts can be applied in diverse contexts and varied ways. I also want to say that I think that it takes a text like HoH (very thick books) to do justice to a poker topic. Furthermore, I think that Harrington really only scratched the surface of his topic.
I think the content is good enough for most low-level players, but one would need quite a bit of creative application not covered in the book in order to do well at a big-time tourney.
I could be way off-base here, so someone please correct me if I am wrong. However, as someone who has taught before (not poker), I can tell you that it is really difficult to do more than cover the obvious in a 30-60 minute lecture.
