(disclaimer, i haven't developed on GAE, I've just read the specs a few times)

yes, that's a problem. In your specific example, the tutorial you
link uses Django-mptt, which uses aggregates, which aren't supported
by the datastore in GAE.

so, I see only three solutions:

- keep searching for a GAE-specific example. I'm sure somebody
somewhere has done threaded comments on GAE...

- switch from datastore to Google Cloud SQL. it's supposed to be
MySQL-compatible, so the Django ORM should work, no? I haven't read
anywhere if that works or not, but IMHO it's worth a try. unless
there's a cost difference? again, i have no idea.

- develop your own. In fact, hierarchical structures aren't a great
match for SQL storage, so non-obvious mappings (like MPTT) are needed.
Google's datastore might (or might not) allow a more direct approach.
