I found that there was basically nothing that I could find which would allow me to mount a filesystem as if it was natively connected securely over the local network without going to real enterprise stuff I either couldn't understand or didn't have the hardware for.

Everything I found was basically FUSE style things where it looks kind of like local storage but any time you want to use advanced features or high performance it would fail.

SSHFS was secure and easy to set up but was maxing out the CPU on my NAS and also did not support file permissions.
