FTL provides a block device, on which you put a 'normal' filesystem.
JFFS runs directly on the flash.

You don't need both, and FTL is patented in some jurisdictions so you're 
not permitted to use it on non-PCMCIA devices.

FTL and JFFS can't actually tell what the underlying MTD driver uses to 
talk to the flash chips. So it doesn't matter.
