I feel the need to add a good example of the media understanding enough about to screw you over.
Over here, we pay a small fee on every blank medium (from printer paper to DVDs) than can be used to copy stuff. At a time they even tried introducing it for RAM, arguing that there are "temporary copies" created in RAM. In return we have the right to create "private copies" and distribute small numbers to friends (rule of thumb says around 7 and you must be familiar with the people you give them to).
Then the lobbying began to change copyright laws and just as Hodgman said, it was now illegal to copy anything with a copy protection (there was a wording about "effective copy protection" which I bet has been removed by now, because obviously if you can copy it anyway, it wasn't that "effective"). As a result, everything is copy protected, we still pay that fee for everything, but the "private copy" thing has become purely hypothetical.
In short: don't underestimate the amount of legal stuff companies and lawyers can throw at things. Even if they don't have a clue about the technology they will still try to drown in licenses, just to legally be on the safe side. Particularly if you use licensed art, expect them to enforce some way make it non-trivial to just extract and distribute it.
