I understand your application here is different. But the solution path of 
an "active document" is identical in spirit to the home-brew solution I 
would have constructed for your first application. Anyhow, my ulterior 
motive in replying to your message was to point out the reintroduction of 
the FRPAA, which has far reaching consequences for the communication of 
science and mathematics. Hence its relevance to many, but certainly not 
all, TeX aficionados. Ot to put it another way. If the FRPAA were 
embraced, how will TeX remain relevant in the medium to far term.
