Are you familiar with how Softimage does it? In a nutshell, whenever a user opens a file, a file with the same name and a "LOCK" extension is looked up. If none is found, a new one is created and the users workstation name is written into it, and if one is found, the user is alerted with the contained workstation name.
You should be able to accomplish the same using the method you described. Monitoring changes however is probably a different topic and may not be what you're after, but there are generally two method of accomplishing it; polling or grabbing a file handle. For polling, you could have a look at Watchdog, a library for Python. It should help guide you through what it means to monitor file-system changes.
