One more KitKat feature spotlight for the evening. This time, it's Wi-Fi TDLS. Added in Android 4.4, Wi-Fi TDLS, as Google describes it, is "a seamless way to stream media and other data faster between devices already on the same Wi-Fi network." TDLS, for those that don't know, stands for Tunneled Direct Link Setup.
Essentially, Wi-Fi TDLS allows two devices on the same Wi-Fi network to link directly to one another and share data without burdening the network/router/other devices in the process. According to the Wi-Fi Alliance:
Two TDLS devices automatically use their highest common performance and security features, regardless of the feature level supported by the network. TVs, smartphones, cameras, printers, PCs, projectors, and gaming devices, for example, can connect directly to each other to transfer content and share applications quickly and easily.
