Couldn't tell from the README, does this do any sort of cache management or LRU type thing? In other words, does it fetch the underlying S3 object in real time, and then eventually eject them from memory and/or the backing FS when they haven't been used for a while?

`catfs` is a FUSE FS that can do this for you. You'll need some changes to make it work well. I'll have a friend upstream them soon, but they're easy to make yourself.

Could replace `goofys` with this and then stick `catfs` in front.
