Other media servers have started to officially support the Wii. TVersity is one that looked at in the past for my Linktheatre. The software itself is nice and has an active development community but I want one that will transcode from FLAC (or any other lossless format) to WAV. The only one I've found to do that is TwonkyVision but it's not free.
