has it been sorted out what happens after backend notifications of commits?
e.g.
backend notifies client of another user's commit
client checks if data has been dirtied by user.
if not dirtied, then
   - client updates local copy of xmin,  the data,  and redisplays data.

if dirtied,
 -client fetches changed data,
   and  user is showed changed data , and requested whether to :-
      revert to updated data ,
revert to updated data and diff of old data and dirtied data appended, or overwrite updated data. - user selects , and xmin is updated and new client dirtied data created.
