I managed to implement the conversion of all SlideMagic features, including the tricky ones (data charts, image cropping and positioning, speaker notes, etc.) into a razor sharp PowerPoint deck with all shapes, data charts, objects completely editable if you created them yourself from scratch.
(This as opposed to the current PPT conversion that makes a rendering that works as you as you do not touch/edit any of the shapes inside the deck)
Now it is on to debugging and making everything super robust in every possible user (ab)use scenario.
The current setup is in a lab environment and not yet kosher enough for public release. If you are curious, are have a SlideMagic deck that you are desperate to convert, email me your SlideMagic presentation ID and I can apply the new technology for you. The conversion software only runs on Windows, but since it is me doing the conversion on my machine (for now), both Windows and Mac users can submit their decks.
