The plan right now is to provide a 'script engine' functionality that would be 
capable of associating HTML-based content with a given cut.  This will likely 
be a 'version 1.1' type thing, as it largely doesn't exist right now.

Yes.  RDAirPlay doesn't actually touch the audio at all -- all it does is send 
commands to the caed(8) daemon, which is what actually accesses audio 
hardware, streams files, etc.  The full command protocol is documented in 
'docs/cae.sxw' in the Rivendell sources.  In theory, it should be possible to 
extend CAE to support other media types without having to mess with any of 
the other components (although, obviously, some sort of 'video library' 
component would be needed to manage the content).  Mind you, I'm no video 
engineer -- I learned just enough to pass the FCC exams twenty-five years 
ago, and then promptly forgot most of it.  :)

Cheers!
