Idea: configurable keys on the keyboard could send a pre-defined HTTP request, so it could be used to control any API that has HTTP interface.
Example: I would like to send a GET request to this URL when I push the brightness up key: http://192.168.1.50:80/homeautomation/homeoffice/ceilinglight/on/
and send a similar HTTP GET to this: http://192.168.1.50:80/homeautomation/homeoffice/ceilinglight/off
