I think it's possible but unlikely because of the number of legacy
devices that would require SPI compatibility. Right now I am in the
position of drafting a new design that will likely have removable
storage. I am leaning toward the use of a USB flash drive over SD
because of it's greater prevalence - and the USB stacks already
available from Microchip.

FTDI also has the new Vinculum device which looks useful:

"VNC1L also transparently handles the FAT file structure communicating
via UART, SPI or parallel FIFO interfaces via a simple to implement
command set.  The VNC1L device features two USB Ports which can be
individually configured by firmware as Host or Slave ports. "
