I've seen it done on a cellphone (ARM9, 100Mhz), since most of the work is done upfront processing the audio before transmission. It's the same old story, you can take your time pre-processing the signal so that it's quick to decode. If I remember correctly, it was under 10MIPS to decode a spatialised stereo signal, no filtering like reverb or doppler though. I don't know the DSP on the SB that well, does it do floating point calculations, or is it all integer maths? Whether there is enough spare processor bandwidth is another question, as is whether it's a useful feature or a novelty. My gut feeling is that it's the latter, it makes a cool demo, but tiring experience long term.
