I am not sure if I understood your proposal correctly, but let me
propose three tasks that would be pretty natural in eev-land... In all
cases below "explain" means "explain step by step, with links to the
source code and to the docs, and with sexps that inspect the data
structures".

  1) explain what happens when we type M-RET on this button:

       "subr.el"

  2) explain what happens when we type:

       C-h h d d

  3) suppose that we have a function that plays a local copy of your
     video "GNU Hyperbole - Overview and Demo". Let's use this fake
     function instead of a real one:

       ;; Test: (fake-play-oand "2:34")
       ;;
       (defun fake-play-oand (time &rest comments)
         (move-beginning-of-line 2)
         (insert (format "[Play Overview and Demo from: %s]\n" time)))

     Explain how you would implement buttons - choose your favorite
     syntax for them - that play "GNU Hyperbole - Overview and Demo"
     starting from a given timemark.

Is that a good starting point? Note the unusual meaning for
"explain"... how would you use Hyperbole to prepare these
"explanations"?

I'm very interested in seeing your suggestions! Can you be more
concrete?
