The idea of it seems interesting to me but it will probably be a crap show. I'd be interested in reading a book though of what life is like in an overseas embassy.
Mostly boring, handing out visas, getting American tourists out of jail, spying, etc. Then of course you have the American Embassy in Iran and other hot spots. Life can get exciting when you and your family are quickly hauled off in a military chopper having to leave all your crap behind. This stuff would make for a great show on the Learning Channel, but it sounds weak for a tv series.
