Yes, since Maxon frequently changes license stuff (Maxon License Server with serial number, RLM without serial number, Maxon License Server without serial number ...), we decided to switch to an independent license model, that uses the system id of the hardware for validation. So you have indeed to export/examine the systemids of the machines you want to use with the plugin. The advatage is, that this id won't change with future C4D versions, so you just have to do it one time, resp. when you change the hardware.
One license can be used on two systems, this is a concession to users running 2 computers, e.g. office and laptop.
