Jesper - I run the risk of being accused of pushing a product (that I have no connection with), but a new product appears to have come out that might be just what you need.

Pretty sweet little device, and with it emulating a Squeezebox, it’s a cheaper alternative to the Aries mini AND has an LPS, which the stock mini does not. Much less expensive, and - I’m guessing - a close sonic equivalent.
