That is the kind of thing a service like Akamai does for you.  They 
store copies of whatever images or video you want on servers all over 
the world and when someone makes a request the data is drawn from the 
server closest to the requester.  Go to Akamai.com for more info.  
Otherwise I agree with Hans, you can't do it.
