       A "site" is a required part of any VOS application.  Its
       responsibility is to represent this application to other sites
       on the network.  Once this site is constructed, it will be
       accessible by connecting the port which it opened (the default
       port number is 4231).  When we create the site, we must supply
       an access control policy.  This is used to determine if a
       read/write operation is allowed on this site.  For this
       tutorial we are using a totally insecure policy which allows
       anyone to do anything.  */

       have anything else to do, so we just call it forever. */
