A question I'd considered for an "Ask HN": Conference call quality sucks, even when everyone is on a a supposedly high-quality landline. I find that I spend so many cycles decrypting voices that I can't concentrate on the discussion at hand. Given all the nice $100-ish USB microphones and such out there, is there an opportunity to build a conference call system which makes it tolerable to listen to the person speaking?
