Hi,

One of my first Lisp projects was a link type that behaves a bit like 
what you describe.

I don't bother with placing the snippet inline, though, I just flash 
it as a message in the minibuffer. But I also leave it on the kill 
ring, so I can C-y it into my current buffer if I like.

The following quick and dirty adaptation to your inlinefile idea comes 
with ABSOLUTELY NO WARRANTY.

#+BEGIN_SRC elisp
(defun my/org-inlinefile-get (file offset length)
   "Copy the line at OFFSET and LENGTH extra lines from FILE."
   (let (beg)
     (save-excursion
       (with-temp-buffer
	(insert-file-contents file)
	(forward-line (1- offset)) ; Go to beg of range
	(setq beg (point))
	(if length 	
	    (progn
	      (goto-line (+ offset length))
	      (kill-region beg (line-end-position)))
	  (kill-line))
	(yank)))))

(defun my/org-inlinefile-open (path)
   "Open a link by displaying the lines specified in PATH as a message 
and making them available for yanking."
   (let ((parts (split-string (org-no-properties path) "\\(::\\|\\+\\)"))
	file offset length beg)
     (setq file (car parts)
           offset (string-to-number (or (nth 1 parts) "0"))
	  length (string-to-number (or (nth 2 parts) "0")))
     (my/org-inlinefile-get file offset length)
     (message (format "%s\n%s" path (current-kill 0)))))

(org-add-link-type "inlinefile" 'my/org-inlinefile-open (lambda (path 
desc format) desc))
#+END_SRC


Yours,
Christian
