To be clear, ITO are not proposing to write this bot but we would be happy
to encourage and support it to happen if there is a general mood that it
would be useful and achievable.

Don't worry - this will only happen once every three months when the OS
publish an updated OS Locator file. We updated to the latest OS Locator
version (dated November 10) last night, hence a few places have fallen off
their '100% perch'! We should be due another one reasonably soon I guess and
may get it up sooner.

In time I hope that we will find that some of our 'not:name' reports will
have been fixed by the OS. I hear that the OS is getting much more receptive
to this whole Open Data thing. One layer I would like ITO to produce would
be the reverse OS Locator view, which would be for the OS's use (and our
amusement!). It would show all the named roads that are in OSM but which are
not in the OS. They would then need to research why that is the case and
update their own products (without compromising our license).
