I had an Eye-Fi card in my DSLR years ago and had a python script [0] running on my home server that'd download the photos as they were taken. It'd play a noise over the home audio system to let the taker know that the photo had transferred.

It worked fairly well but at some point I got nervous that it might miss a photo and switched back to a boring SD card.
