Where does Apple Configurator store ipsw downloads?

Every time Apple releases new iOS software, it's a bit of a rush to get things downloaded and the servers can be slow in delivering the bits. I would like to know where the Apple Configurator Version 1.2.1 (169) stores downloaded iOS software so I could transfer the files from iTunes or another computer so I can have several machines grab one each of the builds and then distribute them to avoid having each machine have to re-download all images each time. Can I move IPSW in to or out of Apple Configurator rather than having it control the downloads from Apple for iOS software?
