Yesterday, in a meeting on the beutifull Novell office in São Paulo, I was able to confirm that ODF is their document standard. Globally, for all Linux and Windows users. If they need to exchange documents with customers, they send in PDF.
I supose Red Hat, a 100% Linux company, is also in this direction. I just didn’t have the chance to confirm this with the folks I know in Red Hat. But I’m pretty sure its the same. By the way, Red Hat, together with IBM and Sun, is member of our local ODF Alliance Chapter Brazil.
