WHS 2011: FLAC and DNLA to audio receiver

I have a large FLAC collection stored on a WHS 2011 box that I would like to have available via my network connection to my Onkyo receiver. I also want lossless to lossless transcoding if transcoding is needed. And it is my understanding that DNLA does not support FLAC, so if I wanted Lossless that the FLAC files would need to be transcoded to WAV. I also want these files to be available from my WHS 2011 box without having to be logged in a user account, as i run my WHS 2011 box headless in the closet and don't want to keep the Admin account logged in for security reasons.
