As Tom Sgouros has answered, this is really hard.
The header/footer thing is probably easy, just as Tom Sgouros
suggested. A paragraph identifier as the first string in the first
line of the page is really very very, needing knowledge that
(AFAIK) is difficult to access.

I guess that Donald Arseneau's


("first word/ last word") can be used with an additional trick.
(Attach a string to that first word, with a negative \hspace.)

-- Uwe.

P.S.: lineno.sty perhaps gives some ideas, together with
The TeXbook and the LaTeX source about output routines.
A not released version of lineno.sty is near putting that
identifier into the margin.
