So you're going to end up with a specialised filesystem instead, I suspect. Basically, it's the same as your do-everything-through-/proc/self/fds/ approach. And it's going to be heavier. I don't know if you're planning on creating a superblock each time you do an O_ALT open, but you will end up creating some inodes, dentries and a file - even before you get to the reading bit. David
