>> And I thought having a write-only scp would be really interesting
I think you can achieve that at the file system level. At least, a long long time ago I maintained a public server with exactly that functionality. I’ve forgotten the details now but if I were tasked with this today my first attempt would be add a sticky bit like we do with /tmp: chmod +t dropbox/
If you don’t want to allow me to delete or overwrite my own files I believe (but haven’t tested) that chattr +a on the dropbox dir would achieve that.
