Yes, even the President has an app for that: >
Today, we’re excited to announce the new White House App available for Apple iPhone and iPod Touch. The White House App delivers dynamic content from WhiteHouse.gov to the palm of your hand.
One feature that stands out is live video streaming. Now anyone with this app can watch the President’s public events at the White House, frequent web chats with Administration officials, and other events like key speeches and press briefings in real time.
