Or does using them according to the interchange spec require FTL?

(That is, it would be really cool to finally have a supported MTD device 
that doesn't need to be soldered on to the motherboard, so I could plug 
the thing in and run UBIFS / JFFS2 / whatever.  I wouldn't be able to 
use it for a camera, then, but it would be great for little machines 
that don't need full hard drives, or for developing MTD filesystems on 
readily-available hardware.)
