Across the internet, you loose access to multi-cast only discovery.  So, your client must use unicast and the service must advertise/join a unicast capable lookup service (Reggie).   I’ve used Jini across long distance network paths for quite some time, and it works just fine as long as you use unicast (direct IP addresses).  For outside of an intranet access to an intranet lookup service and then for access to the discovered service, you will need to take firewall configuration into account most likely.  Port forwarding will be required if there is an networking barriers such as NATing routers etc.
