I made a first step at above module (see my last journal entry) by implementing what I need myself
Python and PHP both have DTAUS implementation. The PHP one, however, doesn't have documentation and the python implementation uses CSV-Files as it's API. There is a nice Ruby implementation, though. I think I'll steal it's API.
The API is a tough thing anyway. The first question that arises is whether to use english or german words since the format is solely used in the German banking system and it is sometimes hard to find exact english translations for all the special words.
Ah, well, back to work
