That assumes you sell software and service as a package. Why not decouple them and take the opportunity to create a new service relationship? Even better, develop the software on the assumption that it will be resold and create a "secondary operator" install procedure that transfers the service relation to the new owner. Instead of waiting for them to call you, you have real-time information about how your software is changing hands in the market. I recognize that the effort may be non-trivial. At the same time, if the law is opening a secondary market - and it turns out to be significant - wouldn't that approach allow you to tap it?
Yup. I see disruptive opportunity, but I hate to see it driven as a reaction to a court judgment. However, many game and business software vendors have been heading this way anyway.
