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.
