Shared Publish Vault?

I and my friend want to both edit my publish site vault. I’m in Texas, he’s in Australia. How do we do this? I have a publish subscription and currently my vault is on a cloud folder. Should I make a "shared Dropbox folder? In other words, how can two people both edit the vault in real time, and then one of them (me) push the publishes to y’all’s cloud? @moderators
