title: Programmable Wifi Relay / Power Switch?
body: <p>I'm toying with the idea of a pet project..</p>
  
  <p>I wanna make our coffee machine remote controlled by a web interface.</p>
  
  <p>The idea is to hit a "make me coffee button" and have it poll the router get the MAC address list to see who's in the office and send them a growl notification (we all use macs) asking if they'd like coffee and then doing something with a relay to turn the coffee machine on..</p>
  
  <p>Can you recommend a programmable wifi relay or small embedded system for this?</p>
