That's awesome. I wish I could. I'm a technical writing consultant who does grant writing for nonprofit and public agencies (www.seliger.com if you're curious), and everything we get from clients and public agencies is a Word or Excel file. Everything we send out has to be in the same formats.
We're in a situation similar to the graphic designers and photographers and so on who say that everything they take in and send out has to be Photoshop / InDesign / etc. compatible. The industry has standardized around these programs and formats and perfect compatibility is mandatory.
LibreOffice is great. I've mentioned it in class (I adjunct on the side), but I can't use it.
