Why would you want anything but read access?

I think random access is overkill. Keeping the code simple is more important and user-space can post-process it.

Auto-resizing sounds like a really bad idea.

And why can't you do this from that code? It just needs an initcall-like thing that runs after mounting of relayfs.
