These 2 are related, so both have to be done to reduce the latency.

ices already flushes audio out every second. In 2.0.1 you can state in
to change the default (which is samplerate). icecast 2.2 also rebuilds
vorbis only streams, but that isn't changeable from the half-second
flush currently. Most of the lag is in the icecast->listener buffering
