As far as the channel layout issue goes, Tim Terriberry advises me: > There are basically two commonly used channel orderings.

Not so with you. Instead, whoever wants to become great among you must be your servant, and whoever wants to be first must be your slave — just as the Son of Man did not come to be served, but to serve, and to give his life as a ransom for many.” [Matthew 20:25-28]
