Things that could be added: improved compression for small files, garbage collection based freeing of unused blocks, increasing node size to equal erase size. We can add such features for a fee, or you can code them yourself and send us a patch. If I am wrong about compact flashes all having hardware wear leveling so that FAT can be used on them, then you can add wear leveling to the list of features desirable. -- Hans
