actually GUI and Core can reside on different hosts, but in most cases 
they will be on the same machine. It is imaginable that the GUI is on a 
PDA and the Core is on a machine that is providing wireless audio for 
the current room. But I have to admit that is a very unusual scenario.

At the beginning of the project we agreed to define the relation between 
GUI and Core to be 1:1, so the implementation won't be too complex for 
the available time frame (which we exceeded anyway, by the way).

When we continue working on the project (which is planned to happen in 
February/March 2006), we will reconsider the design and maybe we are 
changing it. But our main principle was that the GUI has to be as simple 
as possible. That is not the case if it has to handle RTP.


Best regards,
