I would like to see it in Lame for speech encoding at low bits.

Hmm, I think some rudimentary support is already in Lame. (-Z)

Takehiro is already playing with this.

Which experiments are you refering to?

I don't think this would be a good idea. Then you will easily detect
artefacts listening to one speaker only.
