It's going to depend a bit on what format you're going to use.

If you plan to stream in ogg vorbis, you can use Ices 2.x and accept PCM 
via standard input.  This means you could run a sox effect or ecasound to 
get and compress the sound from the soundcard before sending it on to ices. 
Ecasound can make use of LADSPA plugins which opens you to a range of 
compressors, such as the SWH compressor plugins which I'm told are pretty 

If you want to do MP3 then I don't have any good ideas so far.  Darkice 
doesn't allow either receiving from standard input or inserting processing 
(i.e. starting a subprocess which it sends audio to and receives audio back 
from), either of which would be useful functions, and I don't know if Ices 
0.x can accept PCM via stdin either.

I'd be interested to know how you go.  I've not looked at the sox 
compression effects lately so they might do the job, don't know.
