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.
