I think you are way over complicating this. NFS would do this with a single line

On the HTPC you add to /etc/exports the following line (replace things
appropriately) and start nfs
/data 192.168.1.10 (rw,async,no_root_squash)

Then on the storage server mount the nfs export
mount htpc:/data /local/path
