I believe PIC24 and PIC32 will support USBOTG which can act as a host. I
think the PIC18 can only be a client.

I'm using MMC/SD to hold configuration data. It works well! There is one
generic SD card (no label) that I found that works on my netbook, but does
not work with the PIC SD card code, and does not work in a PM3 programmer.
Otherwise, all is well!
