An phone/web app that allows you to click on a place in google maps and request a "cammer" for x minutes, you pay $x and anyone running the software on their phone that is near that location can accept the offer and start streaming video from their phone to you, allowing you to have a kind of "live" street view.
There is UI for the payer to click on arrows to inform the cammer to move here or there, and to zoom or focus on certain things, also a pre translated set of things to help communicate with cammer. Cammer gets paid after the x minutes is up.
Cammer gets cheap money for being a personal camera man for someone somewhere else in the world.
Client saves a trip out there to see something for himself.
Use cases: Want to see if an antique you are looking for is at the markets but cant get away from work?. Want to check out markets in turkey but live in australia? Want to see what the surf is "really" like right now and whether you should bother heading out? Police work/chases! heaps of uses.
For popular events and markets, a cammer could setup shop and offer high quality streams etc.
