This is how the DAZ license works.

DAZ sells "You" a license to use the software. This means you can install a copy of Bryce at work, at home, on any machines where you could use Bryce. If your wife or child gets on your computer at home or a co-worker gets on your work computer you are breaking the license because they need their own copy. If Analog-X shows up in your home and starts using Bryce, that's OK, he has his own license. If you really wanted to install an infinite number of Bryce's with your Bryce lightnings you could but their is no point.

Lightning is a rendering engine only. It has no front panel or way to create scenes. It only gets instructions from another install of lightning that has been given a scene to render by Bryce. In Bryce 5 the control copy of lightning could also render, but they changed it in 6 so it just tells the other nodes what to do. Lightning won't work thru firewalls. Although it's possible to use it over the internet with other machines the problems with keeping a connection for several hours doesn't make it advisable. Lightning requires a fixed IP address to keep connection with its pieces.

You can use this software on as many computers as you can get to. You can even use lightning on other people's computer that don't have a Bryce license if they'll let you.
