hello i just set up NAS , and forced it to work :) there is libaudioss which makes NAS quite transparent (unfortunatelly it doesn't work fully here, it complains about 'buffer underrun' but some audio is sent, i guess it can be fixed) NAS doesn't use any compression. now i am using it via direct 10Mbit and it uses ~50k/sec for 11kbit 8bit mono... it is quite a lot :)
