It's more of a first draft, and could certainly do with some rough edges being sanded off, but here's a working example of websockets - it will display details of the current video being played. You can just put this in a html file and open it in your browser. Make sure you change the LAN address of your XBMC player in the code (mine is 192.168.0.140), enable websockets in the XBMC settings, and use a modern enough browser - mine is Firefox 21, although it should work from FF 6 onwards. The main catch is that websockets aren't supported on IE 9.
Hope this is useful for someone. Improvement suggestions more than welcome. Many thanks to the XBMC devs for implementing such a cool feature.
