I'd love to see a little tutorial or something on How To Do That. I've
tried it playing around with output buffer functions and I encountered
that familiar phenomenon know as "it doesn't work" (This, in a shared
server situation where there are some php.ini things I can't set)

I did buy Shiflett's book (wow, can't wait for the movie to come out!) and
it seems you can do cool tricks at the protocol level with the
"Transfer-Encoding: chunked" header, spitting out chunks as you go along
(although I've yet to try it), but I wonder how one does it in "pure" PHP
with the buffering functions.

As chance would have it, my scenario is similar to Stephen's -- I'm
sending a message to a bunch of addresses. No more that about 150 or so
for now but it would be nice if this script could (...dare I use the
S-word?) scale up well, and this technique of outputting the page as the
process goes along would help..
