Hey Richard,
"Disconnecting Users" is definitely possible within NI VLM. While it is a simple and straightforward process, there is an extra step involved, since it's not the human (user) that is disconnecting from the network, it's a machine (computer). As such, you must effectively generate a new Computer entry in NI VLM (that will ultimately be disconnected), associate that Computer with a particular User's permission set, and then then disconnect the Computer.
The following KnowledgeBase article details this process.

If this rounds out your concernrs regarding migrating some or all of your licenses to be user-based, feel free to contact our contracts group to make the switch by emailing agreements at ni.com.
