The people of the Faroe Islands were disappointed when Google told them they had no plans to add their language to Google Translate. The response was a lovely community effort of recording single words and sentences by many people on the islands on their phones. Project was called Faroe Translate.
A communal effort in providing aligned bilingual data might work. Of course, not only Faroese to English but Faroese to Danish. (So maybe trilingual data input?)
Would it be possible to permit anybody to create a 'User Defined' language and to input data from scratch and continually build on it. This could be for any language of their choosing for private use?
