Yes, that's true! I've made an Ogg Vorbis streaming external for pure-data (an
interactive audio processing environment, Mac equivalent would be Max/MSP from
Opcode / Cycling 74). Only CPU usage seems to be a bit high to me (15% on a 1.8
GHz machine running Win2k, 21% on a 400 MHz machine running the same system). But
this might be caused by the architecture of pure-data.

Well, I can't help you with your problem but you might want to have a look at my
code. I use de-/reinitialisation of the encoder to change comment tags and encoder
settings (quality and the like) on the fly (i.e. while the stream is running).
To get the code, go to http://www.akustische-kunst.de/puredata/oggcast.html and
download the zip or tarball...
