[Hampshire] SECURE NFS ROOT ?

hello all,

i'm trying to find information about some sort of 'secure' NFS-ROOT Filesystem setup. So far, i'm not having much luck.

I have working NFS-ROOT machines, but as you may already know NFS is not encrypted, and i can quite easily intercept packets with code of my own.

So, what to do ? Do you know something ?

tia,

Isaac.
