Ok, the first is more or less what I thought (and what i need), mix them
together in the "local" studio (where will exist the broadcast server,too)

mmm ... but I confused with  "... mount as a source at the broadcast
server...". Do you refer each remote location will have an streamer client
(pc) to send their signal (through Inet) to the broadcast server? or another
way?

They want only a central broadcast server for controlling and planning the
kind of  programs (and to mount them).

OK.. I'm digesting ;-)) ...

... and analyzing ...
* I will have a broadcast server (bcs).
* this bcs will have various soundcards (n +1 -> N speakers + 1 final mix)
* the output of each soundcard is put into the analog mixer.
* the remote clients will send the signal to the bcs (through liveice?) .
* these channels will be received by bcs (and not broadcasted) and will
output them to the analog mixer (one channel per soundcard).
* The local speaker (or producer) will mix all and will send the results to
the bcs.
* the result will be broadcasted ...

right?

More doubts:

- about soundcards: are important terms like "latency 0"?or MP3 decoding by
hardware?, do you know  RME digi9336? can you recommend me any soundcard?

- Do you know if it is possible to control an MP3 file list  manually
( for example if someone want to launch these files one by one and on demand
while mix the rest of remote channels - it could be another pc playing as a
MP3 server ... )

- the rule 1 soundcard = 1 remote speaker isn't fixed, right?. If the number
of speakers grows I will have some way to mix various sources to the same
soundcard. yes?

one bcs routing various "channels" to each soundcard is possible with one
icecast server or I will need N icecast servers on the same machine?

then it's all guaranteed !!!  ;-))
