Hi! I'm a user of the excellent Airfoil for Windows/Mac App.
This particular Blog entry from the developer is interesting as it details the plans for Airfoil, planned streaming of your favourite content to Google's Chromecast devices for example.
I wrote asking if DLNA devices were being considered but haven't received a reply as yet.
At present Airfoile streams to AirPlay and Bluetooth devices. http://weblog.rogueamoeba.com/2016/03/01/airfoil-and-chromecast-devices/ -- ********** Those who don't need help are prepared to help themselves
