Just read that Germany's new IT-Council announced today that they will introduce ODF in the federal public administration. All federal public administrations should be able to receive, sent, read, and modify ODF documents until beginning of 2010. It is already published on heise and golem (both in German).
FWIW, I think the reason was not the German Bundestag decision from 5. Juli 2007 to support Open Standards -- no -- he has seen the pictures with the tart Vice-President Steinmeier got from us at DFD in Berlin ;-)
