Results haven't been great so far but I'm pleased to say it is better than Mark Pincus.
I'm off to connect some LEDs and relays and see if it can turn them on and off.
I think this is a future for computing: remote UI, ssh-able services machines.
But it is also a bit messy, because the NAS exposes files as Upnp, Dlna and smb.
We have 1 Pi at home running RaspBMC and it's great. The thing I like most about the Raspberry Pi is that you can swap out SD cards and reboot, and suddenly have a totally different machine, doing something totally different.
That's something I was wondering about: is there some state inside the Rpi itself? If not, then a system backup/restore is only a matter of dding on the SDcard.
Plain Raspbian for the NAS/music player, plus Samba, mpd, minidlna.
I am not perfectly satisfied with RaspBMC however. I'd rather build the thing myself, piece by piece, so I have only what I need and know what to change when my needs change.
I have a second one and I just recently picked up the Adafruit LCD kit for the Pi, so I'm hoping to have some more fun with that soon.
