You would have to ask the PDF experts (e.g. Adobe).  However, if you saw the
demo (or heard about it) at the Seybold publishing conference, it was done
there.  We (Adobe & Netscape) demonstrated a prototype browser implementation
which treated PDF as a first class object and included streaming and byte range
retreival via server CGI.  Ari is simply attempting (for Netscape) to help
create a standard means of doing this very common procedure so that there are
not 100's of different implementations -- the other very positive aspect
(especially from Ari's point of view) is that if there is a standard way of
doing it, his proxy can understand it...(and cache it...etc...etc...)

One problem with a new method or a Header based method is that it breaks
all existing proxy setups...
