Plugins with their DSP part coded in a language that gets interpreted by the kernel? I think that would blow up the kernel and introduce a lot of complexity. I don't think DSP code is as simple as network filtering code. DSP code needs not only multiply ops but also FFT and inverse FFT.

Think of the Java Virtual Machine - how huge it became and how long memory leaks were a common problem with Java applications.
