Hurray! Great to see this work coming to fruition, and thanks to all the folks that made it happen.
In the spirit of sharing, I'll kick things off by sharing a small realm status web site, written in Ruby using Sinatra. You can use the site at http://wowstatus.info/ and the source is available at GitHub at https://github.com/BinaryMuse/wow-realm-status. It fetches and parses the realm status API on the server side, and caches it in a memcached instance for five minutes before it attempts to re-download fresh data.
I look forward to seeing what everyone comes up with! Happy coding!
