If you can afford to pay big bucks for the Cube than you can afford to insure it. Why would you pay tens of thousands of $$$$ for a new sports car and not bother about insuring it. It's the same thing with The Cube. It doesn't make a whole lot of sense to me not to insure it.
I find that here in the states it's atually rather difficult to find anybody to insure software. VSL is different because they will replace your software for 1/2 price. That's makes it easier to find insurance for their products because the insurance company doesn't have to pay full price to replace the software. I know my Homeowner's insurance will cover my VSL products in the event of a fire or if my dongle grows a pair of legs and walks away. However, if I lose my dongle on the road somewhere I'm S.O.L. (Sh!t Out of Luck). Therefore my poor dongle will never see the light of day. .AFAIK, if your dongle is damaged, you can send it to VSL and if they can verify the licenses on it then you just have to pay for another key. I could be wrong on that though.
Errikos touched on something when he mentioned the "chugga chugga composters" out there. VSL is in the unique position in that there are not a lot of musicians out there who use orchestral samples and it's just not worth it for a hacker to spend all of that time and effort trying to break a difficult code for something that has such a narrow market place. Who is he going to sell it to? He'll go for the easier target like EW or Symphobia and, as far as the Chugga Chugga chimps out there are concerned, East West is good enough for them.
Aside from insurance I don't know what the solution is. This log in every 60 to 90 days idea would be a pain in the A$$ for me so I'm not for that at all.
