Here's my 2p worth. VA is a commercial piece of software, for your money, you get a licence to USE the software, not OWN it. It's called an EULA (End User Licence Agreement) which is used by all commercial software manufacturers.
It's their choice, but VA should consider adopting an online form of registration, like with Adobe and Macromedia software. You type in your serial number, it gets sent over a secure connection, and VA could send back an encrypted key which is automatically re-interpreted by the software as properly registered. This is done in such a way as to not infringe on that user's privacy - the user still has the option of registering his/her email address and contact details to receive offers, and be notified of updates. Adobe offer you freebies if you register, there's nothing better than a free gift for your trouble!
In the past few years, I've noticed that these EULA terms have changed with the times - many people now have more than one machine at their disposal, perhaps a PC at work, and a laptop to take work back and forth. Certainly, Macromedia software came with an EULA that entitled you to make 2 installs of the same software on seperate machines, and only pay one fee. Perfectly commonsense approach. More of the userbase are having more than one machine these days, it is something that should be considered also, even if it means taking a cut in income.
From what has been reported here, Mr Torrens' actions are not going to be looked on favorably by the courts, when taken in unison with my above comments. Perhaps a look on the internet for similar disputes such as these will help him see the light. The comment made by another member, regarding Mr Torrens' credit card company is a good one, although the implications for VA financially could be bad, would their credit rating be blacklisted as a result of something like that?
All in all, a storm in a teacup. If Mr Torrens is concerned about intrusion, it's a bit late now isn't it? Our lives are intruded without you even knowing it!
