I confess, I hadn't considered anything quite so bold as reading the whole
of the text into Lua and then processing it back out. I suppose I was
expecting one of the true TeXperts to offer suggestions involving
\appendtoks ... \to \everypar.
I also realized that I forgot to mention that I want to be able to do this
all while using the ConTeXt project/product/component support.
Any other suggestions on how I could process unmarked paragraphs in Lua?

Hi all,
I am wondering if and how it might be possible to catch all unmarked
paragraphs in a TeX file and pass them into Lua. So, in the following
example, each of the first three unmarked paragraphs would be passed to
the
Lua function process_paragraph for optional processing, but the fourth
paragraph between \startmarkedparagraph...\stopmarkedparagraph would not
be
passed to process_paragraph.
If you are willing to add some more markup, then you can do
\starttext
\startMarking
...
\startmarkedparagraph
...
\stopmarkedparagraph
\stopMarking
\stoptext
where \startMarking .. \stopMarking passes everything to lua (
http://wiki.contextgarden.net/Programming_in_LuaTeX#Manipulating_verbatim_text_for_dummies)
and you can then search for \startmarkedparagraph ... \stopmarkedparagraph
in lua.
Or you could just redefine \starttext ... \stoptext to do the capturing.
Something like:
\let\normalstarttext\starttext
\let\normalstoptext\stoptext
\def\starttext{}
And in the lua end call \normalstarttext before starting typesetting and
\normalstoptext after all typesetting is done.
