> Git would be useful in replacing email-based collaboration, but the switching costs seem too high.

Git was originally designed on an email based workflow for software development (hence the commands am, format-patch and send-email).

For contract negotiation, if the template contract was in plain text, then it could be emailed as a patch. The party would then apply that contract to their local git repository, make the changes and email the diff from the original template back to the first party.

So essentially, you could still use email, but have the diff between changes as the content in those emails (along with inline comments).

Unfortunately, corporate Outlook/O365 based email systems don't work very well when used in that fashion.
