I'm guessing that companies that have restrictions on the number of installs will be flooded with requests for additional keys about the time Win 7 gets sunsetted. All the folks that get botched upgrades will need them. Its about the same as the old lost/broken/fried dongle issues. (We had issues at work with those foolish things years ago).

FWIW, that was another point in Reaper's favor. I've got a copy of my license key on a flash drive and if I need to reinstall, it's a quick copy and go. I think I still have keys somewhere for Cubase LE5 and 6 but don't really use them.

I can understand companies trying to limit theft, but when it comes at a cost of serious issues for paid customers, they need to rethink their methods.
