I think such a shell-script wrapper around an emacs-client or emacs
batch Org-mode instance sounds like a very nice idea -- and not overly
difficult to implement.

Here is a quick approach to implementing the org agenda example you
suggested below [1] notice that the script is structured to dispatch on
the first command, currently only "agenda" is implemented but it
shouldn't be difficult to add others.

Also, rather than a single org script like the one attached which
dispatches based on its first argument, we could go the git path i.e.,
we can have org-agenda and org-add in the same way that git has git-log
and git-push.

#
#   2. make this file executable
#
#   3. run one of the following commands
#
#      org agenda fmt   ## where fmt is one of txt, html, ps or ics
#      no other commands yet...
