Sadly not feasible as it requires interaction for synchronisation
(or file monitoring) and the synchronisation direction varies, as
well as the possibility of "collisions" with the likelihood of two
users (finite probability) wishing to make changes to the file

The direction of synchronisation also varies unpredictably. It's
not like there's one master file that's copied and only read on

rsync is currently being used for other files where there's a master
copy at head office and the branches get a read-only copy on their
server. It works well for that.
