Bob, about your point number 5. Up to five bodies are supported. You just have to register all of the serial numbers. Check the bottom of the purchase page on the website for more info. This was a major factor to my decision of buying the software since I will most likely get a full frame camera at some point in the future (5D3 where are you!?!?!) to supplement my 7D.
Thanks qwRad for clarifying----I'll ammend the original post
