How exactly does runrev for ipad/iphone work?

If I were rev, I would choose the revPlayer App option.  This relegates stacks to source-document status, (not unlike ebooks, pdf's, .txt, html, IM, .snd, .mov, and other source data protocols).  Apple would wind up in some deep deep legal poopoo if it was seen to restrict document access and display on their devices.

Steve's frustration with Adobe has overrun his ability to think rationally.  What surprises me is that nobody at apple had the balls to tell him so and stop the madness before it left campus.

The world's legal systems protect (US first amendment) free speech and content authorship such that source content can not be messed with or restricted to or tied to exclusive protocol.  No one can tell William Shakespeare what type of pen he can write with or printing presses he can publish with.

In the world of sound recordings, there has always been enough purchasing venues (record stores) to provide the requisite freedom of expression and publication.  But when Apple ties content source to player they are violating the same laws that worked against Microsoft's browser integration scheme.  What apple used to get away with when it was the little guy no longer applies now that they dominate the media player landscape.

If not, there must be some way to build the rev stack to iphad app work flow such that rev developers are both within Apple's requirements and are protected from the complexity happening behind the scenes.
