If they will give me a record of what they checked I will send it to you. As for now, I can barely get updates on my car. Thanks for the help!

At this point I'm as stumped as the BMW engineers.

This makes the most sense to me, and so far your car's problem is the closest I can find to mine. BMW head tech (and apparently the engineers now) currently doesn't think it's the clutch.

Of course, my service department has proven incapable of even properly performing a routine service, so at this point I guess I wouldn't be surprised to find out that they can't figure out a slipping clutch.
You're correct, as stated before, the engine revs along with the tach.
