I know there is a great plugin for wordpress that is actually great for links like that.
another thing that I know that was just released is a free link directing script. Made by the same guy that did tevs tube script. I'll find a link later.
edit:
nevermind simple google found it.

he's calling it tracking adult links sytem (tals).
so then you can change certain things out real easy in the future.
