As it is a 3rd party application/plugin and not Renderosity based it would likely be just listed in the Requirements section of the product page on any product that would require it. As in 'this Product requires X plugin for installation'. Their are many items in the store that already require 3rd party products/applications to function correctly. So as far as I can see it wouldn't be adding anything new, other than having the negative buzz word association of 'Encryption".

But don't take my word for it, only Renderosity Admin could truly say if they would plan on adding any additional sorting or markings methods to their store front to indicate items that use this system. And I suspect it may be to early to give an official indication of what may happen in the future.
