That's why I have been beefing up the DOM filtering code in the latest versions -- there are already sites doing this.
There is a lot of untapped potential with the new operators, I am waiting for opportunities to put them to test, and fine-tune them if needed.

Isn't it all done through CSS selectors? Could you share more?
How about leveraging other heuristics such as HTTP headers (response cookies for starters) or timing information?
If you can't filter on classes or id's, what else? Dom element ordering? Image size properties? Structure of ad text?
