I would like to invite Microsoft to publish, with no strings attached and under the GPLv3, the full and complete specifications to all of the .doc, .ppt and .xls formats. All the various incarnations/versions of the formats should be placed out to the whole world and have it published at sourceforge. Let ooxml fail on its own. I will be more than happy to help in getting good ideas from the .doc, .xls and .ppt formats added into ODF to make it the one Global Document Format that we all need. Enough said.
