Suggestions for NAS to Stream flac

[Aqualung]

Any suggestions for a NAS that'll allow FLAC streaming? I understand that streaming FLACs requires transcoding, so I imagine the NAS should be quite capable. Will WD's MyBook Live do? TrimSlice? I tried installing ArchLinux on a Pogoplug E02, but it didn't work out. Even so, I'm not sure it could've handled the transcoding...
