Before we all get carried away, does anybody know how much they are charging for maintenance, and what the costs of the different types of license (node-locked, floating, time-limited) actually are? A time-limited license might be useful. My main worry is what happens to existing, old-style licenses, which were sold as perpetual, node-locked licenses with no ongoing support charge. Will I have to choose between either not upgrading the instrument firmware after some specific version, losing my existing licenses, or being forced to pay maintenance for them? If so, how much?
