As others have stated, I wish there was a bit more information about the service on the page. I use Dropbox and GDrive, but I'm not particularly fond of either of them. Aside from a slight price difference, what makes Copy stand out?

For example, I have a 1Password file that I would like to share amongst my team for all service related passwords. Keeping this in sync with all of our devices is a serious pain, and often results in certain members owning it (usually me) and thus having all of the responsibility.

It doesn't have to be 1Password. I have tried other apps like Keepass with similar results (and web-based versions, I do not like -- security etc.).

I realize that this is hard. Version control, multiple access to the same files and associated updates but it would really be a killer feature.
