Does anyone know how this compares to Coursera course [1] or [2] + [3]?

I've taken Dan's crypto class ([2]), so I think I can weigh in.
Obvious difference: not organized as a MOOC. Whether that is good or bad is up to you.
Focus difference: I think Crypto 101 is targetting applied crypto more, whereas the Coursera classes take a more classical introduction. There is nothing wrong with either approach, in my opinion. Just a difference in focus.
Udacity also has a applied cryptography, I haven't tried. but it's good if someones has feedback.
