IkonTools have cracked open the casing on an Eye-Fi and identified the components. The Eye-Fi is an SD combo card that contains 2GB of flash and and WiFi adapter all in the size of a standard SD Card (which would be flush mount in our Zs) Hopeful one of the wonder genius programmers that hang out here can hack up some drivers for our lovely Zs.
