If the Mac version of Windows Office 2007 has it you could try using the save as PDF XPS.
The default option for PDF output is tagged PDF (in Windows) so, if available, try it.
You will have to perform the "real" V&V" on the tagged PDF with Acrobat Pro.
Otherwise you'd have to do the complete job manually.
You may have to consider an alternative authoring application that has proper tag management support.
Regarding reflow on mobile devices. Keep in mind that PDF is "page" centric.
So, a standard letter/portrait PDF page could be awkard on the smaller screen of some devices.
Be well...
