Chrome Remote Desktop
Chrome Remote Desktop is moderately interesting for what does today -- set up an RDP-like or LogMeIn-like connection between two consenting PCs. With Chrome Remote Desktop, you can take control of another PC or allow another PC to take control of your PC simply by running the extension in Chrome on both PCs. It’ll even go cross-platform between Chrome running on Windows, Mac OS X, and Linux machines -- as well as Chromebooks, of course.
What’s far more interesting is the apparent (near-term) future of Chrome Remote Desktop. It looks like Google is hard at work on both iOS and Android versions of the extension. Soon, Chrome may hold the key to cross-platform communication.
