Somehow I am not convinced that this will work and not result in a fiasco like 
Microsofts product certification. (Try replacing your graphics card and have 
fun with re-enabling your (legal) windows copy.)

Why not make your trial ware have less features? A good feature to leave out 
in the trial ware is the "Save to file"-feature. Or do it as some sound editor 
once did: at start-up present a dialogue-box where only two of a list of 
feature-sets can be chosen per run.Maybe combined with the disabling of 
"save"...
