Realtime Transfer (Stream) the Audio to "another mobile" device "directly" without any in-between components? How to do if I want to play some (any) sounds on one device, and then want another device to hear the same thing at the same time?

And what i also mean is to be able to connect "directly" (via BlueTooth or WiFi) by not using any in-between Server or any such components. Or, should i say point-to-point? P2P? (Lets say without Internet)
There are many apps in the market which you may use to achieve this;


StreamFurious
ServeStream


Both app require you to posses access to a ShoutCast server. (which is a server technology to host what you broadcast. learn more). Services like listen2myradio provides such services for free. This will allow anyone in the world to listen what you play, realtime!

You may also use bluetooth (with apps like Bluetooth Music Player) or wifi (with apps like WiFi Audio Wireless Speaker or WiFi Speaker) if you want to stay at a limited area.
