After introducing a Creative Commons add-in for Office, they are now adding a capability to translate the Open XML Office format into the Open Document Format - see the post by Brian Jones:
Today we are announcing the creation of the Open XML Translator project that will help translate between the Office Open XML formats and the OpenDocument format. We've talked a lot about the value the Open XML formats bring, and one of them of course is the ability to filter it down into other formats. While we still aren't seeing a strong demand for ODF support from our corporate or consumer customers, it's now a bit different with governments.
