Caroline,
we are still running the site with ACES (
http://dev.iued.uned.es) but we will start the migration to dotLRN in 1 (or 2, hope less) month.
Before summer, the http://miempresa.net site (maintened by http://www.mirabase.com) was running under dotLRN half-translated to spanish, if I remember well, but it seems to be unreachable at this time.
On this point, we are interested to participate with the i18n initiative, I don't know if this project has started yet or not.
