Another interesting idea people were discussing recently was a "construction/repair beam" weapon for spacecraft. Using nanites or whatever space-tech-magic we got.
Fire it at a building that is under construction and it will apply some labor to the construction site. It could even take materials from the spacecraft's hold and apply it to the construction site too.
Then it can also do the same for spacecraft, when fired on a spacecraft it could repair damage and replace broken modules with new modules from the spacecraft's hold.
