I think that's the ideal approach, assuming the notion of 
"body-consuming filter" includes content-handlers (and also
that output filters could get at the apreq-parsed input data
if it was available).  It'd be great if apreq-2 users didn't 
need to pass the parsed data around via pnotes (that's what they
do in 1.0).

Pragmatically speaking, the filter API is completely foreign to me,
and I'm sure it would enforce some additional discipline on how
we handle the buffering of POST data.  It'd be really nice if one
of the resident experts were willing to lend an ear to the apreq-dev
list.  We can't keep bothering Stas, well at least not *just* Stas :-)

Heh, feel free to swipe/rework everything in apreq.[ch]; that stuff is 
only there because I couldn't find an appropriate ap(r) replacement 
(apreq_getword will probably we bagged in any event; it's misnamed, and 
I think we can do without it).  I'd rather not have an apreq.c file at 
all :-)
