Cut embassy costs

Here is an idea I like - a Virtual Embassy. Hillary Clinton says she wants to create a virtual embassy for Iran, since the US and the Iranian government can't seem to reach agreements. She states the embassy will be for people in Iran who have questions about the US or might want to travel here. The Iranian government said they will continue to disrupt electronic computer and phone connections. Hilary calls this the "electronic curtain."
Carrying this virtual embassy idea further, we could cut huge amounts from the US budget if we made a lot of the embassy services around the world virtual. We could still have a few American workers in these countries, but the costs could be cut dramatically. In addition, when a US embassy is targeted in an attack, there would be little in the actual embassy building and all information would be stored outside of the country, so little data would be lost and injuries greatly reduced.
I hope we explore further the virtual embassy.
