Further prodding with my Logik IR100 has revealed that not only does it already have (afaict undocumented) Ogg support, it also has IPv6 support enabled, meaning that when I plug it into my normal wireless segment it suddenly gains a real IPv6 address, thanks to radvd. Of course, this is absolutely useless at present, but it's pretty cool.

The Ogg support is more useful; I've now installed samba on my music holding machine and the Logik quite happily scans the share and plays the tunes in the kitchen. Now to see if it passes the Katherine usability test...
