I don't think the actors have too much of a choice, since they're just actors. Brian's right, in that the rising costs are what will ultimately require it to either end gracefully, or get cut off before the producers want it to. In order to continue, it will have to go with whichever route will be able to distribute it and offset these rising costs in the process. I can't really see internet TV being that distribution method until it's far more mainstream than it is now.
