Is it possible to use the SD-WIFI in other applications besides uploading photos? I think it would be very useful for other devices. I would like to see this used in other ways then just a camera. $100 for 2 gigs of memory and a WI-FI could be very useful in embedded applications, not just cameras.
If you're worried about backing up photos while shooting, I rather not have all my photos uploaded to a site. What would be nice if cameras, or the sad card, use Bluetooth to connect to a laptop near by or even a portable HDD in your pocket. That would make sure you have a hard copy of you images near by, and I prefer that. I wouldn't want to wonder if I do or don't have a backup on some server in France.
