Something like this could be made too:
Darmowe Porno,
XXX Movies Tube - Free Porn Movies at iXXX . com
These are custom made, I think. They get a lot of traffic, it looks like it is something that works (buying traffic, selling traffic to tube sites, traffic trading, I am not sure; I mean, I know it general how it works, but I did not look into this yet). Having something like this "out of the box" could be very good.
Edit: There are scripts like that out there already, that can be bought, I think. AdultSearchScript.com probably. You actually had something like this before too...
