Is it possible, either through VBA or interop / VSTO, to automate the "compare presentations" feature of PowerPoint 2010? Simply invoking it would be a start, though ideally I'd like a bit more control - and in the perfect world be able to programmatically retrieve the results.
PowerPoint 2010 lacks the macro recorder, and thus it's not possible to use the old trick of recording a macro, executing the operation manually, and then looking at the generated code. PowerPoint 2007 has the macro recorder, but doesn't support the compare presentations feature.
I think the answer to this question is probably "no", but I'd be delighted to be proved wrong...
