On UNIX this sort of thing is typically done with a virtual file system.

That sounds too fancy. If it operates on a given directory, you can write a very simple wrapper shell script to do that with tar.
Isn't it normally done with the similar technique of LD_PRELOAD, which unlike a vfs can be done from userland?

You can implement and mount such virtual FS entirely in userspace using FUSE.
