StarOffice 8 and E-Business Suite

We are currently evaluating whether Microsoft Office can be replaced with StarOffice 8. For this one of the steps is to define how E-Business Suite will be affected. The first thing which comes to mind is export to excel functionality. E-Business Suite has this functionality in XML publisher, Discoverer and Web ADI. I have logged an SR to find out whether Oracle certifies this officially. Will update more when I find out.
