I run Squeezecenter software on a NAS, which also stores my music. I have a Squeezebox classic plugged into it, which is plugged into my Decware Zen. Everything is controlled remotely by using iPeng app on iphone.
My next purchase will be the Vortex Box. Rip, store, and serve all in one "appliance".
I'm not sure how this compares with the Olive brand, but wow, what a price difference.
