RMVLICKEY

IBM states (in the help text and Info Center for the RMVLICKEY command):

"Removing license information from the repository does not affect installed 
licenses. Any license that is currently being used to access the product on 
this system remains valid and usable."

As far as I can make out, if you uninstall a licensed program (with 
DLTLICPGM) and remove the license key for that product from the repository 
(with RMVLICKEY), this does NOT actually get rid of the license from the 
repository. It might not show up on WRKLICINF, but its still there, and if 
you subsequently reinstall the product (with RSTLICPGM), that product will 
work just fine and will continue to consider itself licensed.

So, my question is: is there any way of deleting a license from a system so 
that the product is no longer usable? If not, how does this affect the 
licensing of software when a system is put on to the second-user market? 
Doesn't this mean that there is really no way of transferring a license from 
system A to system B, because there's actually no way of effectively 
deleting the license from system A?

Am I missing something?
