There seem like a lot of logistical issues but there are some opportunities as well. Because delivery is so quick, customers might be expected to wait at the designated delivery point or no delivery will take place. A smartphone might well play a role. You order your pizza, and when it's ready for delivery you receive a notification that you have five minutes to get outside. Once outside the smartphone might also be used for verification purposes via some sort of wireless connection. Still lots of ways for things to go wrong, but I bet there are some interesting solutions. It's all very new. Or, hey, as long as we're spitballing, what if it were common to have some sort of household bot? A butler-bot, if you will. It might have the responsibility of ascending to the roof (via some sort of track) to take delivery. You might need some sort of defenses against burglar-bots but ... I think I'd better stop here. ;)
