;D I think we have a lot good news in this topic: - Cameron told us that for future products, we'll have an automated re-activation. Human contact and e-mails are fine, but are also a lot of work for the author or vendor, and that can make support costs very high. I guess most questions you have to answer are about keys and about the DRM, not about bugs or add-on problems. But, even with the best possible support, customers from other timezones may have to wait a few hours for an answer. An automated re-activation would make it possible to re-activate the product within a few minutes. When I was using Windows and FS2004 I bought some Flight1 products. With their website and with the e-mails you got after the purchase, it's very easy to get a new key if you change your hardware. - We learned a lot about the DRM inside the MU-2. We can reinstall the product if we need to do it, and we can ask for a new key. The DRM is just used to activate or enable the product like a serial number and we're entitled to use it for as long as we like. So engines will not stop because we were using the add-on more than 4 hours per week, or because one day we'll be in 2011. - For now, X-Plane add-ons are a "niche market". If this changes, the use of DRM may be "re-evaluated". I really hope this will happen, not only because of the DRM, but also because it will make it possible to create more and more high-quality add-ons for X-Plane. It will also make sure authors and vendors will be well paid for their hard work and talent. - I'm happy to see that something has been prepared in case of a major problem with X-Aviation. I hope we'll never need this key utility and that X-Aviation will last forever. But if not, customers may still have a solution from Google if X-Aviation ever goes out of business. So SimSoftWorkshop's story will not repeat here. - Tom agreed that information about the licence should be available before people buy the add-on. I think this is important. And I even think the licence should be "accepted" during the purchase or a least during the installation. Hobofat is right when he says people wouldn't read it. Most people will not read it, they will just scroll the text and click "I agree" if the website or software requests it. But I think it's important for the vendor to make sure it has been displayed on the customer's screen. Without this, in some countries you wouldn't be able to tell a court that a customer did violate the terms of the contract. For now it's easy for him to prove he never saw this contract and he'll say he didn't know that he was not allowed to distribute the software (and to sell millions of copies). And it's important for customers to know software is a like service, it's not like hardware you really own, you can sell, share, or give away. It's important for them to know what the licence allows and not, that authors are behind this software and that they have rights. Young generations don't know this and don't care about this... sometimes they even don't know that they're sharing their complete filesystem on P2P networks. But that's another big problem. Now I have a question... you decided to use DRM and I respect that even if I don't like DRM. But can this technology make it possible to release a time limited demo of the MU-2 ? That would make it possible for customers to try the product before they buy it (like the X-Plane demo). I'm not sure, but this may be an additional way to show Flight Simulator users that excellent add-ons are available in X-Plane, and that X-Plane should be something else than just a "niche market".
