Hmmm.   It seems to me that the goal is to provide a new kind of document --
one that includes as part of the document transitions to new pages,
for passive reading by readers who might be distributed all over the
place.  I can see how you could automate a slide show for one station
using remote control, which solves the immediate case, but what you
want is a general way to "play" this sort of program to any readers
who want to click on the relevant start button.

Ie it seems to me that it's perfectly reasonable for FREQ to be a
candidate HTML tag.  It's a new sort of attribute for a document,
extending the document metaphor a bit beyond what's done with paper.
(But I agree that if Hytime or something else has tackled this it'd
make sense to look at the other examples.)
