Basically: will there be a major performance hit if we replace the echo
cancellers with an array of function pointers or something similar? Even
being able to set the echo canceller via a module parameter would be a
step in that direction.

(And the obvious observation is that non of the current echo canceller
modules works well enough for a large enough subset of the cases,
right?)
