For now the output functions of Embperl can't handle binary data. What you
can do is, set optEarlyHttpHeader (must be set in your httpd.conf), so the
headers are send, before the page is generated. Now you are able to use
mod_perl's output function. You can simply use print (not [+ ... +]) to
output your binary data.
Another possibility is to write a small Apache::Registry script which
handles the request and does the output, since there seems nothing todo for
Embperl in this case, as far as I see.
