Cesare, I really appreciate all the energy you put into that topic, but I have the feeling that you tend to over-complicate things a bit. :-)
The ladies and gents of VSL support are known for their friendly and helpful attitude. Seemingly disastrous occurrences can be solved by a simple mail most of the time - with significantly less bureaucratic hassles than you would have to go through when dealing with insurances (!) or elaborate download/time limited/challenge-response/hardware-based/otherwise nifty "self repairing" license schemes.
Believe it or not: VSL is not a bunch of greedy and malicious people with the only goal to torture and squeeze customers. Most - if not all - of us do this because we like to do it, and because we hope that other people could like our ideas too. While we can't please everybody with all aspects of our products, we try to find the common denominator between "technically advanced" , "musically inspiring" and "economically feasible". In the case of copy protection, we have what we have. In an ideal word, we wouldn't need one; without financial restrictions, we would have written our own (the PERFECT one, of course! ;-) ...); in Real Life, we have chosen the Synchrosoft / eLicenser system because it is the smallest evil amongst all possible solutions (and a pretty safe one, too).
I know by now that you would like to read "You're absolutely right, we have to do it exactly the way you want us to do it". While this could happen in many feature- and sound-related discussions, I'm afraid that our elbowroom is tight as far as copy protection is concerned. 8-)
... that said, I'm just a sound guy, and maybe there are already other options I'm not aware of just behind the horizon.
Kind regards,
