How about some odf?
And this last days i have been working on some mocks and other random stuf, all exyting stuf i assure you ;). I also have some perliminary versions of mime types for ODF Stlill neads some work i know :). But tell-me what you think in the frist place they are a bit off the general oxygen mime types, but it does IMO integrate well the odf logo, so im unsure.
