Even though Lucent does it in the kernel, the proper place for that sort of signal processing is in userland anyway... makes the non-trivial problem go away in a jiffy :) -- Jeff Garzik | May you have warm words on a cold evening, Building 1024 | a full mooon on a dark night, MandrakeSoft | and a smooth road all the way to your door. - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org
