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.
