It sounds like you are repeating or restating the old ARC issue. ARC doesn't always work and while it's nice when it does I don't spend time on that anymore. If it fails I connect up the other ways. Some clients want me to try and if they do, we state the going rate for trying, have them sign the second page of the service agreement and most bolt at the cost. That is, they let us hook it up in any way that works.
