Push request to Yún

Hi and thanks in advance for the help.
I've just got a Yún and am starting on a project to remotely invoke it to move a servo, either by sending an email or tweet.
I've got the servo element up and running on an Uno working from a push button.

For the connectivity/web call part I've been looking at the option in Temboo and it looks like the Yún will need to be configured to check on a set period (e.g. every 5 mins) which will cause the reaction to be very slow or use my Temboo allowance up quite quickly as I'm a cheapskate :slight_smile:
I was wondering if there were any options to push to the Yún instead via these methods, or whether there is another recommended method instead of email/twitter that would enable this?
For example could you expose a web service from the Yún?

HTML5, Arduino Yun and AngularJS: build a mobile servo controller

  1. create an HTML5/Phonegap/ChromeApp application able to control Arduino from a mobile device from a local WIFI (main topic of this article);

  2. send/get asynchronous data from/to Arduino from remote networks;

  3. get realtime data from Arduino;

Amazing - thanks so much for pointing me in this direction, it's exactly what I was looking for. XD
