About step 11: how B is to know what part of his own version he has to
copy to the clipboard?  Is this by comparing A's version with it's own?  

When the activities will re-open in the same shared-state they were when
closed, it might be very useful have a function to let A and B check for
diffs and merge their two versions - without doing manually.

There might be an "easy-merge" mode where conflicting changes are just
ignored, and an advanced mode where A and B can resolve the conflicts.
