What is your flexibility in offering a fixed, flat perpetual license with annual maintenance, or other pricing models based on users or other metrics?

If the business case warrants it, we’re open to a perpetual license or alternate custom pricing models, provided the fee is adjusted based on actual usage at some level, and has a correlation with value that is measurable through a verifiable metric. However, this is exceedingly rare and only under special circumstances (for example when Orion is used for a purpose other than protecting revenue).
