if you can make your external program talk nntp protocol,
you can use nntp.el by setting the server's
nntp-open-connection-function to a function like this:

  (defvar nntp-my-program '("sloop" "-p" "-d" "-q" "bach"))
  (defun nntp-open-my-program (buffer)
    (save-excursion
      (set-buffer buffer)
      (erase-buffer))
    (apply 'start-process "nntpd" buffer nntp-my-program))

(this is what I'm doing in my first try at a compressed
reader protocol.)
