Yes, the echo cancellation code is very experimental. The algorithm
implemented (MDF) is very efficient, but it will *not* work out of the
box yet. Right now, it's mainly missing a cross-talk detector and some
tuning of the adaptation rate. I can't give a target date at which the
code will work, but if someone with echo-cancelling experience
volunteers to help, it might happen faster.
