Oops, it seems I missed the thread "multilingual presentation with org" started earlier this month, my apologies for coming back to this topic.
I would like to add that the idea of using a special markup (using some symbol) that would accept an argument (the language) would be cool. I'm thinking something like &en: This shows up only in the english version& &pt: Hey! This is not portuguese!& Or even a compound statement &pt: Português &en: English&fr: Français& Carlos
