It's hard to say whether that would work without knowing the landscape of market in that area, like if there's a need and if there are competitors. It sounds like what you're suggestion could be a full blown app with accounts that link to AWS? Or would it be a tool lib you pay to download?

I'm trying to look for ideas that won't require marketing or anything other than just making the software. It seems something like a donation based business model or a small fee perpetual license, and it would be for end users, but so far it seems those are extremely rare.
