The issue isn't just interfacing to SD, it's implementing the FAT
filesystem as well. If you just want a chunk o' FLASH, SD is easy.
If you want a filesystem that would allow you to pop the card into a
computer and read files off it, that's a different animal.
There's also a USB host shield and corresponding library for the
Arduino. I don't know if they have mass storage code yet.
It does interface to some USB/RS232 chipsets including, IIRC, the one
in the D72.
