Power down reliability of such data is an absolute must. I expect embedded 
systems using NFTL and ext3 to be absolutely reliable even if the plug is 
pulled half-way through a write.

This means we end up with two separate journalling / logging mechanisms - one
at the block device level (ext3) and one at the flash media level (NFTL). As I
said - ideally, we ditch that in the end and have a journalling/log-structured
filesystem directly on the flash media.
