If I understand it correctly, the Vue Inf serial number is tied to the Lightwave Serial Number. So if its not tied to the dongle, it apppears you could resell it. That is of course if E-On accepts the registration by someone else other than a LW purchaser. What I mean by that is, if NewTek supplies the LW/9 registration details to E-On, the person buying Vue may not be eligable for upgrades to future versions. Of course that's just a guess.
