If this NAND filesystem is similar to others I am aware of (e.g. 
JFFS2, UBIFS), it is intended to be used directly with NAND FLASH 
devices (i.e. a chip).  This is common for embedded type applications.

USB Flash Disks are a type of SSD and are arranged as logical disk 
blocks.  They are not suitable for use with a NAND filesystem.

Regardless, the availability of a NAND filesystem will make FreeBSD 
much more competitive for use in embedded applications (where Linux 
currently dominates).
