title: sending/receiving broadcast messages over VPN connections
body: <p>I'm in the process of building an application that will work on a bit large network so I'll have multiple subnets .. The network will be working over VPNs, so I'm thinking of having it to work as hub-and-spoke (I know this is a bad design, but I have some ideas to overcome the negative side)</p>
  
  <p>Now, the most important thing ... I need to have the application to send broadcast message to every subnet in certain events (App close, App crash, ...) this is to allow remote Apps to use an alternate plan that I will be implementing as well.</p>
  
  <p>Note: I'm in the network/application design phase, so I don't have any code ready yet. It would be great if you provide a working code sample (exe file would be great to test as well).</p>
