Such a plain file is terribly inefficient and has bad
performance for any significant number of users.

I would recommend to use a real database (e.g. PostgreSQL).
It has several advantages:
 - Good performance (with proper indices).
 - No problem syncing between MXs, they simply access
   the same database (or a replicated one: most databases
   already support replication themselves).
 - There already exist solutions for users to edit their
   own data in SQL tables.
