Wireless Memory Card
Although this isn't directly concerned with open source, I predict a lot of clever open source coders will start hacking this system and doing interesting things with the idea:Eye-Fi Inc., a company dedicated to helping people navigate, nurture and share their digital memories, today unveiled the Eye-Fi Card — the world’s first wireless SD memory card for digital cameras. The Eye-Fi Card uses home Wi-Fi networks to create an effortless and convenient way for users to send photographs directly from digital cameras to PCs, Macs and online photo and social networking sites.
