It's called the interwebs. You know, you could just stay home and have your freakin conference using your thousand dollar world-leader webcams instead of making a security mess of my goddamn city. Really, world leaders. Really. There are literally sh*t-flinging bandits running around because of you, I'm not even kidding. Actual human fecal matter has been thrown at people. No wonder they're spending a billion freakin dollars on security for a 36 hour event. /minirant
But if you are making any buisness deal if you make it in face to face the chances of the deal going well are greatly increased. It's the same for a situation like this where each person is an abassador of goodwill and world peace. If everyone linked up on the interwebz then it would increase the chances of WWIII! :shocked:
