I would love to say there is something really cool on the horizon, but at this stage there isn't. The ProntoSqueeze module has taken 3 months to write pretty much taking up all my spare time.

I hope to get back to some Denon modules I started which comunicate to the amp using the Ethernet port vs serial.

Also interested in looking at creating a SlimServer using the new ASUS PX20 which is a low power (18W on CPU and 5W on idle) very small (2 Litres). They are quite cheap (AU$550) and very quiet too (25dB) and it even has a built in speaker!
