you might adapt this: https://github.com/bbatsov/super-save

it saves buffers when they lose focus. You could also have them commit and push with a little more work.

I have a similar situation to you (4 machines, using git + unison) and
sympathise.  I have managed to be careful enough that it works for
me.  However, using a remote server could be quite easy using Emacs
remote access capabilities.

For instance, you can have your org agenda files include remote files:

(setq org-agenda-files '(
  "/ssh:a.remote.hostname.org:/home/user/myremotefile.org"
  "a.local.file.org"))

this will work nicely *if* you have a robust and low latency connection
to the remote server.

Of course, the other solution is to use some proprietary cloud server as
somebody else has already noted.
