Dumb question to check you have thinks right.

192.168.0.2 templeofthebeard is the NDS server here, isn't it?  The
machine running nfsd!  If shrineofthebeard is the server then you are
only allowing it to share the directory to itself.

As you have names for the machines I suggest that you use them!
Try changing the /etc/exports (assuming shrineofthebeard) to:

/home/public templeofthebeard(sync,no_subtree_check,rw)

BTW: What do the options sync & no_subtree_check do?  I don't have them
on my Debian system.

I agree, and has he as a simple network this is okay, but bad practice
in general as it allows anyone to mount the /home/public directory and
that then gives them access to the files.

I tend to agree, he is making progress very slowly.
