BBC News has bureaux in 39 foreign cities - but only in one can we go anywhere, anytime and broadcast live for radio and television using the web.
So where is this technological nirvana - Tokyo, Los Angeles, Brussels?
The answer might surprise you - it's Kabul. The city is one of the first in the world to be a giant wireless zone. Using "wi-max" and a trusty laptop, correspondent Alastair Leithead can broadcast from pretty much anywhere in Kabul - and all at a fraction of the cost of traditional satellite links.
Using a small black box on the roof of the car, the team in Kabul can pick up a 512k broadband signal right across the Afghan capital - and all powered from the cigarette lighter in the car. Gone are the days when we had to fly out staff and equipment from London to make this stuff happen.
Why does it matter?
Because Afghanistan is now rivalling Iraq as one of our biggest stories. Thirty British servicemen and women have been killed there since June. The BBC is the only international broadcaster to have a permanent presence in Kabul - and by harnessing the latest technology, it means that money we used to spend delivering the news from remote places in the world can now be spent on gathering the news. And that has to be good news.
