RSS Feed Advertising

From News.com, about Kaboodle BrightAds RSS

On Monday, the company introduced a self-service system that lets online publishers pair advertising with their RSS feeds. Called BrightAds RSS (after the technology format known as Really Simple Syndication), the service takes advantage of Kanoodle's keyword advertising system to match Web content to relevant ads. Once a publisher signs up, an advertising link will piggyback on its syndicated feed sent to third-party news readers.

Echo's of the Google Toolbar debate? It sounds like Kanoodle BrightAds RSS will create and host RSS feeds for their customers, and intersperse Ads in the feeds. I am not sure this is a good idea , but I suppose it was inevitable. The question is, will the inserted ads be distinguishable so that an aggregator could strip them out?
