I have two suggestions:
1. A "lite" mission editor or mission builder tool that a user could use when they're travelling but still have the bug to build missions without having to have the entire DCS World program installed on their lesser capable laptop or travel computer. It would allow mission to be built and then produce a mission file for loading onto their main sim computer. Perhaps even an online mission builder portal that is a web based GUI/UI? I'd pay a small subscription fee for a service like that.
2. An online/web based portal or standalone program where a user, on a laptop or lesser powerful machine while travelling, could assume the role of GCI/ABM/AWACS in multiplayer servers.
