License Tracking for Dongle License Keys

[bottsrm]

When creating a license that the license key is in a dongle or usb what is the best way to record this license. We have a publisher that the license is on a usb and can be move from one device to another.  Would it be best to use node-locked concurrent user or appliance. I am really not sure which is the best for tracking the license.

@bottsrm  Seems Node lock concurrent user license is best in terms of you will have control on license. but other side you need to check the financial budget as well.
