Two of the major challenges displacing PPT with interactive tools, particularly in consulting, market research type of business, where large 100+ slide decks are common, are going to be the (1) need to produce decks on clients' templates and (2) need to email decks.
The direction in which a few emerging CSS/JS based tools (slides, reveal, etc) are going will not solve that problem. D3/WebGL etc. are awesome, of course, for the web. However it's relatively rare when a busy exec will have time to use non PPT based deck.
In what kind of business? This sounds like totally atypical in any modern enterprise.
The average user probably lacks this knowledge though and wouldn't know to or try to double-click on an html file but it is technically feasible.
