Thanks, here's my ugly code that seems to work:
(defun status (msg)
(interactive
(list (substring (let ((count 0)
(inhibit-read-only t))
(minibuffer-with-setup-hook
(lambda ()
(delete-region 8 (point-max))
(add-hook
'post-command-hook
(lambda ()
(save-excursion
(goto-char (point-min))
(when (looking-at "\\([0-9() ]*\\)Prompt:")
(delete-region (point-min) (match-end 1)))
(let ((str
(format "(%s) "
(length
(buffer-substring-no-properties
8
(point-max))))))
(insert str))))))
(read-string "Prompt: ")))
7)))
;; post to identica
(shell-command (concat "/home/jac2349/laconica.sh ") msg))
