Of course a 'Yes' vote will also mean that Scots will no longer be allowed to buy tickets for the National Lottery; they'll need their own Lotto game, with a (proportionate) weekly jackpot prize of £150,000. And with much better odds, that'll send them into a lotto frenzy in Inverbollack.
But of course they won't be able to use the .uk internet top-level domain tag. However, most of the esses have already gone; Sudan's got .sd, Seychelles have got .sc, and .sa, .sb, .se, .sg to .so are taken, as are .sr to .sz with one exception. The only codes left for Scotland are .sf, .sp, .sq and .sw.
And instead of the international +44 dialling code for the UK, they'll need a new 3-digit code (all the 2 digit ones have gone). I think +856, next to Cambodia, may be free. They'll need phones quite a lot, as Scotland won't be able to afford a postal service. In contrast, Royal Mail's costs will plummet once it doesn't have to maintain daily deliveries to some of the most isolated homes in our archipelago.
Still, I'm sure the new SBC will make some fine TV and radio programmes, not at all parochial. After all, some very good TV has been made on the tiniest budgets. Talk shows, mostly, but still. And once they manage to convert all the Sterling vending machines to whatever new coinage they'll be using, they'll even be able to buy rail tickets to come to the UK and watch our TV whenever they want.
I'm sure they'll have much more to thank Mr Salmond for.
