Hacking
Very nice - but I have a mental picture of all the bad guys gleefully rubbing their hands together. Yet another system to hack in to, lads!. I dread to think what havoc could be created, as there are bound to be vulnerabilities. If this is implemented, it is going to have to be well locked down - and how! Using "smart" systems on a vital public service such as this has got to be looked in to very carefully.
