a CONS is an object which cares: WebRTC and the File API
Two interesting developments in HTML5 I’ve recently been made aware of are WebRTC (thanks to Manuel Simoni) and File API(thanks to Rich Jones). The RTC part of WebRTC stands for Real-Time Communications, but it’s basically a way to provide TCP/IP sockets for a web browser while pretending you’re not providing TCP/IP. The top-layer part consists of various video and audio codecs, but the basic gist is a way of providing a bidirectional channel for web browsers to communicate with each other. This is accomplished with NAT traversal in mind (the functionality for traversing NATs and proxies in the reference implementation is provided by the very handy looking libjingle library that seems to do most of the common NAT traversal tricks).
