This article about Vivid's adult chat service, VividNow, appeared in today's Chicago Tribune.
Unionized Hollywood actors, animators, and writers have all successfully negotiated for extra money when the job they do for one medium is translated to another. This sort of thing happens when workers are unionized. (Another thing that happens when workers are unionized is that they go on strike and don't make money.)
The only real difference between the non-adult entertainment industry and this one lies in the lack of unionized labor. Everything else is a matter of scale.
There would never be a "and we're going to do this extra scene for mobile phones" scenario on a Hollywood set unless agents, managers and the SAG rep were all on board, too, and the extra work reflected in a paycheck.
That said, parking is always a lot easier on this side of the hill.
