Saw this comment on a news.com post, and thought it was right on:

We are only kidding ourselves if we think we can live in a world where our actions are not tracked. Information about personal activity is the grease that keeps our information economy humming. Knowing what you buy, where you shop, what you watch is the only way to keep our economy efficient and our prosperity growing. I am tracked every time I buy something — I use my credit card. I am tracked even as I write this sentence. If I weren’t tracked in this way, our information economy would collapse under its own inefficiency. Instead of pretending we can avoid being tracked, we should have a conversation about how to track activity in an open, ethical way that does not get in the way of free market competition.

I’ve recently been experimenting with efficient methods of scrolling large display objects (such as sprites, movieclips, or bitmaps) in AS3 for certain projects. I think I’ve built a pretty solid (and easy to implement) solution that should save time on redraws.

Basically, the bitmapData object cuts the background up into stage-sized chunks, and tiles them. Then it uses the the holder sprite’s position to choose which tiles need to be shown. Using this method, I believe that redraw time should be significantly cut down for huge multi-thousand pixel backgrounds.

Let me know if my theory is incorrect.
