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_te...) 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.
