You can have your camera upload the data to a remove system via a
wireless link. There is always a way.. as long as you are willing to spend
the money.
You could be taking pictures in Australia and backing them up in US
almost instantaneously.
I tried that with my old Nikon. Do you know how long it takes to upload 6gb of files by WiFi? It was painful. The fantasy was cool, though. I imagined I could be shooting somewhere like Goa with the shots instantly appearing on the client's hard drive.
