connecting video applications via a packet oriented format over a pipe

I like the idea Charles Yates has about a standard way to connect
different applications that work with videos and other time based media
formats [1].

Regarding the protocol we want to implement for our video-server, I'm
not sure if this is relevant, though. Maybe for that purpose, our
currently planned shared memory based mechanism is more appropriate.

On the other hand, maybe both approaches can be combined by simply
putting packets into shared memory instead of sending them over a pipe.
A frame packet (= image) could look very similar to a plain
image in memory.
I like the possibility to mix different media types that way
(synchronizatiojn of audio and video for example!), and also the
possibility to add extra (meta) information like time-stamps,
frame numbers and so on. If the receiver can't deal with that
extra data, he just can ignore it or pass it through.
It should be possible to also mix in midi and stuff.

Any thoughts?
