There's a whole set of geographicly inclined gTLD proposals out there -- the most famous being .berlin
The intriguiging thing about these proposals is the different way they are being pitched to ICANN. Some are being done by private companies and are being supported by the local governmental officials. Others are being done by city/state or region itself. Other still are the product of cooperation between a series of regional entities (for instance, the well-intentioned .asia proposal.
Don't know much about .scot except that there didn't appear to be at ICANN and yet they remain one of the many proposals in this category. One of the criteria for acceptance is the avoidance of string contention or similarity. Which is too bad because .scoot might have been a fun proposal.
