I haven't done server-push, but I have done immediate write (using
RESPONSE.write(), which is the first thing you'll need.  To be honest,
though, I haven't tried it under ZServer, and I only used it once.  The
tricky bit is that once you start doing "hot" output, any errors are not
going to be output cleanly.
