+Other Apps in testing: [https://shou.tv/ Shou] (root Airplay/DLNA mirroring - works well apart from small lag), BubbleUPNP Audiocast (root xposed sound mirroring over DLNA, 20 minute trial limit), AirAudio (root, airplay/dlna, 5 minute trial limit). All 3 work well, the later two require licences which is annoying. Untested: AllStream, AllCast (untested due to absurd license limits), feel free to suggest others

 * '''February 2014''' - Proper Airplay (with screen mirroring) and Chromecast were installed. An IR receiver and LED was hooked up in order to be able to control the projector remotely. A splitter was attached to the audio line to allow for playback from both MPD and the projector without switching.
 * '''March 2014''' - Synergy and Picast removed due to poor performance. A DLNA/UPnP receiver was set up on the Pi to allow streaming media from devices such as Android phones & tablets. A Pulseaudio sink was also installed. We experimented with an external DSP to amplify sound, however this didn't work. Reverse VNC now runs on startup so there is no need to run script each time.

-The idea is to up an interface/client for the projector, in order to play & display video/audio over the network remotely. This will allow for less shuffling and more compatibility with a wider range of devices, for which we may not have all the cables. It also allows for mobile devices, such as phones and tablets, to share media to the projector directly.

Sending music over airplay works fine most of the time, mirroring works intermittently - seems to depend on the number of devices on the network. Chromecast works sometimes, it seems that Youtube works best right now. Streaming side-loaded google music or any DHCP content does not work.

 ==== DLNA/UPnP ====

 The parts still need to be automated, a web control interface is desirable. Currently the clients need to be launched manually, although this can be done via ssh - scripts are available. More clients can be added as needed, and a further control interface for the projector and stereo system will need to be put in place.
