Great!  That looks neat.

Here is a slight rewrite of your code:

;; Use (current-column)
(defun current-line-length ()
  "Length of a the line at point."
  (save-excursion (end-of-line) (current-column)))

;; Use (org-write-agenda file)
(defun org-agenda-to-file (key file &optional max-line-width)
  "Write the `org-agenda' view associated with KEY to FILE.
MAX-LINE-WIDTH optionally specifies the maximum line width for
the text in the resulting file."
  (interactive)
  (save-window-excursion
    (org-agenda nil key)
    (switch-to-buffer "*Org Agenda*")
    (org-write-agenda file)
    (org-agenda-quit))
  (if max-width (put-file-content-in-procustes-bed
                 file max-line-length)))

;; Use a separate torture function for this
(defun put-file-content-in-procustes-bed (file max-line-width)
  "Find FILE and cut anything beyond LINE-WIDTH."
  (save-window-excursion
    (with-temp-buffer
      (find-file file)
      (kill-rectangle
       (point-min) 
       (progn (point-max) 
              (move-to-column max-line-width t)
              (point)))
      (erase-buffer)
      (yank-rectangle)
      (write-file file))))

Here is what the associated shell script would look like:

--8<---------------cut here---------------start------------->8---
#!/bin/bash

/usr/local/bin/emacs-23.0.0 --batch --eval \
"(progn (load-file \"~/elisp/testing/org/org.el\") \
        (org-agenda-to-file \"a\" \"~/.desktop-display\" 60))"
--8<---------------cut here---------------end--------------->8---

BTW, do you have any screenshot showing geektool/conky in action?

It's not possible right now.  I wonder if this would be useful.  The
purpose of the agenda view is to give you a quick overview of your
tasks, not to burden souls with details...

In agenda mode, you can see the item at point with SPC and you can turn
follow mode on -- this will display the subtree at point.

Thanks for the code!
