Nodeler is a zero configuration service (Apple calls theirs Bonjour) for web and mobile applications. It can be used to pair two applications/devices together in an easy and secure manner.
I'll be opening the API to developers along with posting sample code for using it, including the code for the Chrome extensions.
Ideas on how to use:
-Instead of a mobile version of your site, create a "Full Screen / Media Center" version with remote control.
-Use a mobile phone to control a game or app running on an iPad.
