James: A lot of the workstation systems have their own CPU IDs. That wouldn't be a bad way to handle it if you could work out a way to deal with CPU upgrades. In fact, our SGI machines have the processor ID in ROM somewhere else in the system, so you can swap out the processor board without changing the ID. Our Developer's RenderMan floating licence uses an encoded key that is keyed to this ID. No security is unbreakable, you just need to make it too hard to be worth doing. The dongles are probably the best compromise available now. Chris
