I've made a bit more progress with this. I found a utility, unoconv[1], which I 
can persuade to produce a tab-separated export of the first worksheet of an ODS 
document. That much should work for my needs -- I can reserve the first 
worksheet for the data to be published, and put all the calculations in other 
sheets.

I'm not sure how to import this as an org table. I found org-table-import, but 
it seems that this must insert a table into a buffer and then convert to 
org-table format in the buffer. I don't know how to integrate that with babel. 
If I set ":exports results," should I assume then that the code block should 
return a string consisting of the org-formatted table?

- Or, do I have to say ":exports none" and do some save-excursion magic with 
moving the point to the right place before calling org-table-import? (That's 
probably okay for this small-scale usage, but it would be slicker to put a 
#+CALL in the right location.)

- Or, do I have to write my own lisp function to format the table as a string?

The goal is that I should be able to do C-c C-e h h from the org document, and 
babel will run a short emacs-lisp block to invoke unoconv (producing a CSV file 
on disk) and then insert the table under the right heading.

Thanks,
hjh
