I don't know much about BCI, but I'd imagine not all applications require spike sorting (http://www.scholarpedia.org/article/Spike_sorting http://www.scholarpedia.org/article/Spike_sorting for those who are unfamiliar with this), though of course if one could spike-sort in close to real time, one could do a lot more. In any case, I absolutely agree with you -- at the algorithmic and implementation level, there are lots of nice problems in making sense of neuronal recordings.
