Martin,
is the reason for your question that you want to move from PC to PC with a single license or is it (as indicated) a "security feature that only you can use LV installed on a 'golden stick'"?
The first one is a license activation/EULA (NI sales model) discussion, the later one can be achieved by using VLA with personal licenses.

EDIT: Haven't checked on this, but maybe a personalized single seat license is already sufficient without the need of a VLA......
