Nice try, but even if Canon made a remote wireless shutter release for my point-and-shoot - which they don't - that might let me get out of the building before it was destroyed when the bus blew up, but since the building's inside the bus, the camera would be destroyed as well.
And no - Canon doesn't allow this model to WiFi the image to another location in the instant before the collapse, so you can stop baking me a cake with a file in it.
