I once wrote a small Python script to help me with automating
Git-based deployments, but it's simple enough to be suitable for a
variety of use cases:

https://github.com/xen0n/touchmon

It allows you to specify a hook for each file observed, just make sure
the watched file exists before starting the watcher (a known
limitation). Inside the hook script (any language is OK) you can
pop-up a dialog and store a  timestamp somewhere, if the user has the
file opened for him/her. Then for the periodic notofication, maybe a
cronjob would suffice? Simply check the stored timestamp with the
current time. If polling is not what you want, you can extend the
inotify part to also monitor events like IN_OPEN or IN_ACCESS and
manipulate your timer accordingly. But be aware of false positives
like some background daemon accessing the file, as ALL opens and reads
are watched.

Hope this helps~
