We know they'll invent new scenarios. We know they'll want to save that configuration. With Django's admin utilities, we can do a "dumpdata" that preserves the interesting parts of the the database. That much is …

The obvious answer is that we need a customer-like demo site that shows how the customer's software interacts with our software.

The problem is that it's a totally back-office kind of relationship. Worse, we don't have solid use cases. We have working software for some use cases, but every conference …
