Implements a gateway server to allow barebone basic sensor components to report state change updates as simple via TCP/UDP ports without the 'overhead' of the HTTP protocol. A power sensor for example might just broadcast a four byte floating point binary number once every second to an UDP port or an arduino board sends a UDP datagram whenever a button is pushed. You get the idea, this is how to bring embedded devices into the world of HTTP and Javascript...
Easily create a floating action button interface.
