Check out the definition of \on-the-fly and things like #last-page
and #part-first-page.  IIRC these emails were from 3-5 years ago.

Yes, but we're not having any official discussion about this until
GLISS.  In particular I'm uncertain about the notion of a
\footer{} section, although that idea has come up from time to
time and will be given due consideration.

My intuition is that \on-the-fly already does 90% of what you
want.  If I'm correct, then unfortunately:

1) this won't be good scheme practice at all since it's so easy
2) you'll want to talk about syntax, which is a huge time+energy
drain that we don't need right before 2.14.
