I don't like the idea of out of base swaps, but I would be a big proponent of out of base pickups, and like the earlier example, only after the in base guys have had some time of exclusive access to it.
As it is I have had several instances where I tried to get rid of a trip via personal drop in DBMS and the swapboard and no one took it. Giving me another option to get rid of that trip would be a good going.
