Or does using them according to the interchange spec require FTL? (That is, it would be really cool to finally have a supported MTD device that doesn't need to be soldered on to the motherboard, so I could plug the thing in and run UBIFS / JFFS2 / whatever. I wouldn't be able to use it for a camera, then, but it would be great for little machines that don't need full hard drives, or for developing MTD filesystems on readily-available hardware.) --Andy
