Exposing our data using WFS has certainly prompted some debate, which is good! Particular thanks go out to Andrew Larcombe, who put together a great OpenLayers page, with some nice ajax touches, and a clever mechanism that clusters nearby sites together and reduces the load on the server. We had a few requests to release this data by wms as well, so here is the request for that. The process of doing this has thrown up some challenges, which I think are mostly down to my ignorance than anything else!
