    Sean:

    There are no PICs with Firewire support, but you could use one of
    the USB PICs to build the world's slowest USB-to-ATAPI bridge.

    You'd have to write your own host-side driver, of course, since
    the standard Mass Storage Class drivers that are built into
    Windows, Linux, the Mac OS, etc., won't work with the USB PICs.

    I don't know if anyone's done it with a PIC; just about everyone
    who wants to build a USB-connected mass-storage device uses
    either a custom ASIC or one of Cypress Semiconductor's chips.
