title: Localhost-only RMI?
body: <p>I have a project which starts a second JVM. Currently I'm using RMI to communicate between the two. Works well on my own machines.</p>
  
  <p>I need to be able to deploy this project on Windows 7 machines where I do not have privileges to change firewall rules.</p>
  
  <p>The registry (launched from within the first JVM on a high arbitrary port) is being blocked from opening a server socket on these machines.</p>
  
  <p>Is there a way to restrict RMI to only listen to local connections; such that Windows firewall will be cool with it?</p>
  
  <p>Alternatively, is there a good alternative IPC approach that will require little functional changes?</p>
  
  <p>Cheers.</p>
