Multi-person syncing is something we want to support down the line, but it's a complex feature. We haven't tackled it yet.
If everyone is in the same physical location and the groups aren't large, using Bonjour sync in the manner you're attempting can work. As more folks start to use the apps simultaneously, though, the chances of two people simultaneously editing the same thing at the same time goes up. When that happens, you see stuff like Policarpo mentioned in
post #5. That's what folks mean when they say it's possible but not designed for it.
If you get this working for your team, that's great, though!
