UBIFS was Re: Compressed file system for SD?

[nickd]

I haven't sorry. Coincidentaly, the new kernel which was released the 
other day (.27) includes a new filesystem designed for flash drives - 
UBIFS [1]. I wonder if this could be relevant to this project. It looks 
like it has full write-back support, meaning it doesn't need to write to 
the SD card all the time, although I guess we don't have that much 
memory to play with.
