[linux-audio-user] IP audio transport

Greetings,
I am new to the list and linux audio as I have taken over engineering a 
radio station.  We will be building a brand new studio on campus in 
2008, and I have already started to meet with the architectural 
committee.  The more I consider our mission and where broadcast audio 
has the potential to go in the future, the more I find I would like to 
implement an open architecture infrastructure for the facility.
At this point, one of the largest questions I am facing is the transport 
of the audio around the plant, and potentially around campus.  The UW 
has invested a tremendous amount of effort in building a multicast 
capable infrastructure to handle communications needs of the campus into 
the future, so we will certainly have pipeline available if we wanted to 
get data from point a to b.  The question is what type of transport 
would be capable of interfacing with what type of in-house switching and 
routing?
The in-house needs would be a system capable of replicating something 
along the lines of what Z-sys:http://www.z-sys.com/pp_routing.html 
equipment is capable of providing.  My first choice would be to 
replicate this type of routing in software as well [JACK on a large 
scale].  The question then leads into what will be the transport 
method?  Cobranet http://www.peakaudio.com/CobraNet/Background.html is 
certainly promising with actual market availability, but it is still 
proprietary.
I ultimately envision a system where an artist (DJ) sits at a terminal 
and has the capability to patch their own inputs with ALSA and JACK, 
bring everything up on a control surface for tactile use, and route to 
air, stream, or file.

I welcome any comments in any form which anybody wishes to contribute.  
I will also continue to form my train of thought here:

environment which has been long overdue to the audio world.

Matt
