I think this will force some decent changes... a shift to more unrestricted timed out demos; a shift to revocable license platforms like NI's and ILok's systems to protect developers; better software QA...
Seems to me the one downer is that wave file products, which are truly useful for visualizing and placing impacts, risers, and whooshbangs in a timeline might go by the wayside...things like Alpha, Bravo & Juggernaut... that would be sad. Maybe a developer could offer a locked down file system until a 30 day return expired then provide the waves after.
All in all, a good move... forces some changes and removes the whining rational behind many who complain about protection systems....which might allow more good developers to survive.
