I’m planning to use it in my terminal-based log file viewer (https://lnav.org) to deploy an agent (over ssh) to remote machines to monitor their log files. CosmoC allows me to build a single agent binary that will work on lots of target machines and package that into the main lnav binary. I’ll still be building lnav packages for different platforms, but the agent build and deployment is vastly simpler with CosmoC.

I’ll be using this feature in my day-to-day work because I interact with short-lived VMs running the software I’m developing. Being able to run lnav on my devbox and have it live-tailing logs on the VMs running the changes will be an improvement over the current workflow where I manually copy the files onto the devbox.
