I don't know what kind of work you do to tell you how to be productive, don't even know if you use PCs.
IF your work is primarily PC based, you can talk to your IT weenies about gaining remote access to your internal systems, if needed. For communicating, one word - Skype.

"Let us hope our weapons are never needed --but do not forget what the common people knew when they demanded the Bill of Rights: An armed citizenry is the first defense, the best defense, and the final defense against tyranny. If guns are outlawed, only the government will have guns. Only the police, the secret police, the military, the hired servants of our rulers. Only the government -- and a few outlaws. I intend to be among the outlaws" - Edward Abbey
