I doesn't look like I can use ladspa plugins over the tunnel, or can I?

Especially since it consumes the whole bandwidth allocation whether actual sound is being played or not! Ouch. Well, at least when using an ssh tunnel with CompressionLevel=9 you can reduce that down to around 220Kbit/s when idle. (from 1.4Mbit/s) I haven't tried with single-channel 22KHz yet. </blockquote> Correction, that's ~56Kbit/s idle.

Not bad compared to 1.4Mbit/s!
