Now this is SD 2.0: Eye-Fi, an SD card with WiFi so you can copy your pictures from your camera without removing the card.
The card comes with custom software which installs on your computer and detects when the card is connected to the same network. Then you can copy pictures to your computer and even upload them to different photo sharing and social networking sites.
Of course, there are a couple of hacks, most notably those by Dave Hansen.
The card is already in stock at Amazon for $99 (2GB).
