theoretically possible is far away from practical. That's my point. It would take quite a bit of work to do even subset of what most other solutions come out of the box, at most likely much lower performance (the reason to use cache in first place).
You can put a fucking text files on the disk as cache and `find -atime X -delete` to clear it, doesn't mean you should use it.
