actuall I use a regostered TwonkeyMusic on my PC, but now I will buy a NAS-device so the PC must not run to stream MP3.
Can I use this (see picture: http://img329.imageshack.us/img329/5601/lanfpyy2.jpg) NAS device and install Twonky on it?
Or what cheap device will you suggest?

(The MP3-Client ia a Philips SLA5500 Wireless, the NAS will be connected to the WLAN-Router via LAN)
