I agree with your comments regarding LibreOffice. OpenOffice Calc may be
a good alternative and if people find that it's doing what they need
they should certainly continue to use it. However, LibreOffice receives
many more updates with bug fixes and feature additions. If there's ever
a chance for accessibility in Calc and Writer to be improved we're
likely to see that happening in LibreOffice before OpenOffice.
