Thanks a lot for the answers.
About Q1: i just need to check with enTourage, shouldn't be a problem. Only trouble could be to get the "edge" delivered to the hotel at the same time i'm there
About Q2: Sounds great. same here, will check with enTourage, just to be sure. Updates is the most important.
About Q3: Great about the physical switch, that should be enough, If its approved as a flight mode of the FAA. Then it shouldn't be a problem. Its just a precaution to physically hinder a software accidentally (or willingly) starting the transmitting circuit.
thanks again.
