I just noticed this Slashdot article:

Basically a Judge ordered a film to be taken down from Youtube in part because an actress claims she was tricked into appearing in a film that turned out to be significantly different than what was presented to her, and partly because she was never an "employee" in any meaningful sense.
That seems to me like it could describe quite a few porn shoots, and this is something that could have broad implications for the adult industry depending how the appeal goes and depending on the other factors involved.
