We have a mechanism for installing packages from a central repository - go to
http://dotlrn20-test.collaboraid.net/register/admin-login and then
http://dotlrn20-test.collaboraid.net/acs-admin/install/ and you will see a link that is broken, but Lars will fix it as an alpha requirement. It does direct d/l and install from an openacs.org repository. I think we should use this mechanism for installing new languages or updating languages, but I'm not sure how that integrates with synchronizing new work.
