Awesome, glad someone at least read it. ;-) I guess it does seem like it would be most useful to an online or other informal presentation, rather than a course (where one might expect enough mathematical maturity from the students that complex-valued Hilbert spaces should be a safe place to start.) I definitely have a lot of trouble visualizing said spaces, especially once you get more than one bit, so I think contemplating the contrast between p-bits and qubits will help me get a better handle on the properties of the latter.
