I read a review today and I was just curious before I make this purchase: What I'd like to know is this: I have a company on the East Coast and I have an employee living in California. I see this person 2x a year so I can't always maintain there MacBook until I see them. Does ARM allow me to maintain via the internet even if we're not on the same network. So like when Lion comes out I can do it for them as long as they're connected to the internet? Would I also need to purchase multiple versions of ARM from the Mac App Store or do I only need to buy 1 copy and install a client version of ARM on there machine? Thanks!
