Questions I'd like to see answered are:
Do I have root? Can I install other packages?
Things like this would allow the rededication of this to a media server, for example. For that, you'd want to be able to install Linux packages to, for example 1) allow network booting for a diskless HTPC 2) allow media server software to be installed (e.g. the MythTV product for server, or the linux server software for products like the NetDVD Cinema or even Mac Mini) 3) since it has to be on all the time, run a firewall on there (or virus scanner)
Without these capabilities, it can be used as network storage. Whoopie. I can buy a remaindered PC of similar spec and install Linux on it and get 2TB of storage for the same price or less. And get a better product out of it.
