While I completely understand why you wouldn't want to transfer compiled programs between decks, as that kind of just makes deckers cuboid program factories, it would be nice if you could transfer data such as device IDs, geocodes and known daemons between decks. It opens up opportunities for people to run around with a deck on behalf of a decker, scan some devices, and then sell the data back to a decker who can transfer it onto their main terminal. Or allow a decker to replace some of their hardware without having to make a trek to re-scan all their gear.
