Armory communicates with Bitcoin-Qt with network messages that are independent of your architecture (the same way you can access the same websites on the internet with 32- and 64-bit machines).
Similarly, if you setup an offline wallet with Armory, the online and offline machines don't have to have the same architecture, OS or even same version of Armory! As long as they can read text files!
