This ia simple webapp that runs on your Raspberry Pi to turn it into a remotely accessible Wake/Sleep-On-LAN Server. Follow the detailed tutorial on my website for instructions on how to get this working, and forwarded through a router. This is very useful when you have high-powered machine that you don't want to keep on all the time, but that you want to keep remotely accessible for Remote Desktop, SSH, FTP, etc.
