Finding the nearest public toilet using SMS

I guess it had to come – I’ve tried out SMS systems for locating hotels, petrol stations and hotspots.  Now, one of the London Boroughs has started a system to help mobile phone users to locate the nearest public toilet.

Actually the area covered would appear to be still rather small, but if the rest of the capital joins in then it could be a useful resource.

But will it be any good in rural areas, where public toilets are often locked – the key being kept in local shops?

I’d like to suggest extending the system – to allow such toilets to be unlocked using the same SMS system.  Any vandalism would be easily traced back to the mobile phone owner that unlocked the toilet.

Does anyone else think that this is a good idea?
