I need to do some investigation of bringing the tap count WELL above that... 
I'd like to see what kind of performance we can get with 128 MILLISECOND 
tail...  128 taps is only 16ms...  and 16ms of echo cancel is damn near 
useless, as it's fast enough that you'd likely not even hear the echo as 
anything more than a sidetone anyway.

I imagine it's deathly hard on the CPU though.  :-)
