What a blast from the past. I attempted to build a file-sharing tool for my team when we had video and images strewn across the org. I prototyped embedding filestash for the frontend.
It was basically a backend for generating STS credentials on the fly using a more ergonomic interface. It never went anywhere and I haven't thought about it in years, but I still believe it was a good idea that I just didn't have the organizational clout or time to push forward.
Edit: apparently I contributed at some point too? I *barely* remember that. Glad to see the project is still succeeding!
