No touching, but you can look. Loren Baker from Search Engine Journal was actually able to see my Google RSS Ads after I was approved. He only saw it once or twice but was able to take a screen capture of it for me. I check my feeds very often in both Bloglines, My Yahoo! and Safari RSS and have never seen them. But Loren has proof, which he emailed me. This is the first posting of a picture of a Google RSS AdSense Ad to-date, I believe.
Now if they worked 100% of the time. Just kidding, I am beta testing it for them, so its cool for it not to work. Forum discussion at Search Engine Watch Forums.
Update: Wow, I actually now see Google AdSense RSS ads in my Safari reader.
