I would like to have an offline wallet with Bitcoin Armory on my old computer, and use my other old computer as a 24/7 miner. Further, I would like to mine on my current computer when I am not using it for anything else. I want both of my miners to be able to deposit and withdrawal BTCs to the offline wallet. How would I set this up? I feel like it should be as easy as importing the watching-only wallet onto both computers; is this correct?
