Okay, that's not really the entity group being named, but the root
entity being named.

But *why* exactly do you want to do this? In your original email, you
said "Is there any way to get the hostname, IP, or MAC address where
the GAE app is running?", which is a fundamentally flawed question.
Your App Engine application doesn't run on a single machine, IP or MAC
address, because it runs on potentially hundreds of machines
concurrently. If you're wanting to use the aforementioned details to
get a unique identifier you're also doomed to failure, because there's
no guarantee that there will be only one instance of your application
on a machine at any one time.

If you tell us more about *what* you're trying to achieve, rather than
*how* you think you can achieve it, we can give you a better idea.
