I wonder if this offer stands from semester to semester, and therefore if he seeded an exploit (or several, given how the extra credit reads) or whether the whole thing is just more of his light-hearted style.
But I definitely agree: that course looks great.
Typically, I create a fresh ubuntu server at the start of each semester, and I let it go unpatched for the duration of the semester.

I might put the course online some day, but lectures are extremely interactive.
I'm not sure how well they'll translate to an online format.
A reasonable amount of the course material is in blog posts, and I add more posts each semester.
