I have added an ELPA package for the OpenOfficeExporter here. The archive URL for consumption by the package manager is this: http://repo.or.cz/w/org-mode/org-jambu.git/blob_plain/HEAD:/packages/.

"http://elpa.gnu.org/packages/") | ("tromey" . "http://tromey.com/elpa/") | ("jambu" . "http://repo.or.cz/w/org-mode/org-jambu.git/blob_plain/HEAD:/packages/")) | | Original value was | (("gnu" . "http://elpa.gnu.org/packages/")) | | | This variable is potentially risky when used as a file local variable. | | Documentation: | An alist of archives from which to fetch. | The default value points to the GNU Emacs package repository. `---- I hope it is OK.
