How about being able to use your boot as anyone's dropoff point? Say you've got the car somewhere and someone needs their stuff delivered. They come by, hit an app for authentication, your boot opens, they take their stuff.
Lots of issues, but why not?
What about "AirBnB for package delivery." I don't have this problem (UPS will leave stuff at my house if no one is home: they'll even put stuff inside one of the vehicles if it's raining or snowing), but it strikes me that "renting" out your house for the express purpose of letting UPS/FedEx/whatever drop off a package for someone who can't get packages delivered during the day might be a useful service.
Probably can't charge much per package, but if you're OK with random people showing up at your house to get packages, it might be a useful service.
And on another note, I just saw the first TV commercial for AirBnB. How long have those been running?

In the '/whatever drop off a package for someone' market, I guess you can charge quite a lot, as 'whatever' will often drop of things that aren't 100% legal.
A service like that would need (self)-regulation, just as, for example, eBay and AirBnB developed after some initial bad press due to bad experiences of their buyers, respectively landlords.
This works great in an ideal situation, but there's lots of room for bad things to happen.
