Not quite sure what I'd use this for - when I want to create vietnamese text I use SCIM for Linux; on Windows there is unikey (http://www.unikey.org/); both of these have the advantage of using a regular qwerty keyboard (you have to learn a half dozen extra key combinations to create all the diacritics and vowel marks.
Or am I missing something?
