Yes. We have a special version of Isadora that works together with Sassafras Keyserver, a third-party licensing system used by many large institutions. The Sassafras Keyserver edition of Isadora, which is offered at no extra charge, allows you to install the application throughout your institution, but to run only as many licenses as you have purchased. If you wish to use Sassafras Keyserver, you must purchase it directly from; TroikaTronix does not automatically supply you with this software.
