Hi, I just came across this (very long) thread started by Brian's post, and since (as Robinson Tryon mentioned in a post already) libreoffice can convert both .ppt and .pptx to .pdf, I've now set up the tools servers to convert any .ppt and .pptx to .pdf as soon as they see them. This means that .pdf versions of powerpoint slides in the future should be available at the tools servers a little while (less than an hour) after upload. You'll find them linked in to the WG agenda pages, see for instance this page http://tools.ietf.org/wg/abfab/agenda where the abfab-3.pdf and abfab-4.pdf were originally submitted as .pptx I've set the converter ('unoconv', which uses libreoffice) up to convert to PDF/A, but the converter doesn't always fully succeed in producing valid PDF/A (also mentioned by Robinson in one of his posts) -- the result still works fine in the viewer I've tested, though.
