What about an ad blocker for NIS/NAV 2011?

I wonder how functional it would be for NIS/NAV to have an ad blocker put in? I know I made a post about pop up blockers the other day, but the main thing I am refereing to here is those annoying ad banners you get on websites from time to time. I have accidentily clicked them before and it just led to even further annoyance. It would be really cool if NIS/NAV could utilize an ad blocker.
