The URL it reports on start-up may not work depending on your DNS setup. This should be listed as a known bug, although solving it generically might be tricky (I had some dodgy code before which pulled out the primary interface from the routing table and... well, don't ask).

Find the IP of your box using `ifconfig' and connect on port 8090 to that. If it's a fixed IP, you can modify the $ip variable in the app to report that as the URL for the service.
