I don't see why you would not contact Brent and do what he says, if you have ANY doubt as to whether stuff will work (unless you are trying to offload it and get your cash back).

He has this irritating thing called integrity and dedication (okay, that's two things) and will work out how to get your situation to work.

If Ethereal costs more, consider how much it costs to try something else. Even if only one out of ten installations of other products causes a problem, who needs to be spending time to fight cabling when satisfying things like "finishing" and "collecting the check" can be done?
