I've not seen or heard of anything for FLAC, but I believe this is how Avisynth and Virtual Dub's aviproxy work for AVI files on windows. http://avisynth.org/mediawiki/Main_Page http://virtualdub.org/docs_frameserver.html In those cases, it seems to be a very useful idea which is a bit less than 100% reliable, but invaluable for those programs / situations where it works. It might be easier for WAV than AVI because we don't have as many windows APIs to worry about.
