What made you select UFFS? It licence, or its properties? Care to share 
your reasons to not use YAFFS?

I would be interested to see a UBI/UBIFS port too. My guess is that the 
NAND flash interface required by UBI is very small, and it might turn 
out that porting it to use eCos NAND is trivial. This would mean a 
UBI/UBIFS in user space though, and I don't know how much work that 
would mean, and whether it would be supported by the MTD people.
