Now that my Windows 7 sleeps and wakes up as needed for DVR activities I'd like to see a master switch in the Web UI that would inform all other clients to issue a WOL (wake on lan) when the app is started or moves to foreground. ie, just before the client sends whatever to increment the client count, issue a WOL and wait two seconds.
Ceton "My Media Center" has an advanced option to "send Wake On LAN when on wi-fi and connecting to a PC".
Or, if it's easier, make it an option per app.
