Subject:   -27- The Movie Library has calls to play a movie in a file,
                memory or a file descriptor.  But all of them seem to
                assume that the complete movie is available locally.
                How can I play a movie all of which is not available
                locally?

  It's really not possible at the moment.  The Movie Library
  needs access to both the header/indexing information stored
  in the movie file, as well as the media data itself in
  order to play the movie.

  It may be possible to do this by passing a socket
  descriptor instead of a file descriptor.  There definitely
  is a problem of seeking to a particular frame.  If the whole
  movie is streamed in with no mvSetCurrentFrame() kind of
  calls, it may work.
