Thanks for all your clarifications. I'd like to continue this

Maybe I'm looking for a solution in the wrong place (media framework),
but how would you handle these situations:

1) The user is accessing his machine remotely. He can easily redirect
X Window to his machine, but how does he redirect audio in some easy
way? (e.g. for the blind this is important)

2) The user works on his own machine, but wants the media (in our case
ogg decoding and speech synthesis through an external component) to
be processed on a more powerful remote machine.

It might look a bit complicated, but both are examples of situations
we are dealing with in real world in our organization.

Perhaps this is the current technical state of things, but regarding
the stated goals and design decisions, MAS is much more complex than
just transfering audio. My understading is that it provides a framework
to handle all kinds of multimedia and in many aspects it tries to accomplish
the same as GStreamer.

Why? Because of missing plugins or because of some more serious

It is. I don't know how fast or efectively, but a new release is
being prepared AFAIK.

But don't get me wrong, I personally have many issues with MAS too.

Do you see communication over network as an obstacle to something?
In other words, is this difference a reason why both projects should
