PDF to PowerPoint converter

[Graham Smith]

Although, I have found a couple via google does anyone have  
experience of PDF to PowerPoint converters.

I would prefer a Mac or multiplatform option, but Windows, or even  
Linux would do.

Having now been using Beamer for a few days and been very pleased  
with it as a replacement for PowerPoint, I'm now told that I "must"  
provide my students access to PowerPoints of my presentations.  
However, having used Beamer there is no way I am going back to  
PowerPoint.

Apparently, PDFs, do not provide the same support for accessibility  
requirements (SENDA in the UK and section 508 in the US).  I can't  
see how exactly, but thems the rules it seems.
