How exactly does runrev for ipad/iphone work?

One way to do this is the old runrev virtual machine idea (build and distribute a rev stack player app for iphads).  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.  

Apple has walked a fine line here for years.  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.
