In the meantime, take a look at this OS Maps / Google Earth mashup. This uses tiles from Ordnance Survey’s OpenSpace API. This is one of the features I always liked about Memory Map, and its very cool to see this sort of thing done legitimately for free.
Edit #1: Service disabled by Ordnance Survey
Only a few days after I wrote this post, Ordnance Survey disabled the API key used to to provide the map tiles. Even though the implementation was simply delivery of a KML file which mashed up the OS map and Google Earth entirely on the client side, the OS seem to believe that the developer was using Google APIs and somehow transmitting OS property to Google. There’s more on the developer’s blog.
Edit #2: It’s back
Oddly enough, just after I wrote that last update, the service was back up. Hurray!
