[mod_python] streaming zipped data with publisher

Sure it is, even with the temporary file option, all you have to do is 
set the content-type header to application/x-gzipped or something like 
that (application/octet-stream is always a fallback value; this forces 
download, and doesn't allow it to recognize the file format for use with 
an external application), then output the file (possibly setting the 
Content-Length header first, to be polite)

with or with out the file is your choice, all you have to do is output 
the binary data, and no other output (not even a single space) or you 
will corrupt it.
