I recall some discussion quite a while back in time -- more than two or three years --, where somebody of PG Staff said something like: "We don't mind a second installation if it is the same user." The wording was definitely different and acknowledging that one is working on a desktop at home, but away from home, like on a stage or in a hotel room, it might be used by the same individual on a second computer. Sometimes it is inconvenient to carry an extra external disk, like if you're working on battery these things consume quite some time's worth of energy.
