...ose to (successfully!) use your solution, with a slight difference: I used uuid.getnode() to find uuid of my system. So I'm testing if uuid.getnode() == 12345678901 (actually a different number) instead of the os.environ test you used. I couldn't find documenation to convince me that os.environ['COM...

...
ObjectIds are generated client-side in a manner similar to UUID but with some nicer properties for storage in a database such as roughly increasing order and encoding their creation time for free. The key thing for your use case is that they are designed to guarantee uniqueness to a ...

...0−11), equivalent to the odds of
creating a few tens of trillions of

You can even use the entity identifier for equals and has...
