I posted today at InfoWantsToBeFree on what should be one of the top concerns of all Truly Free Filmmakers in this coming year.
Data Portability (and access) is something that should be built into contracts, particularly when the license fees are as low as they are these days. It's the same question as owning what you generate. It's a question of what is really free in a free market.
There's a lot more to say on the subject and this will be a big topic for discussion here and elsewhere.
