I'm of the mind that no one has tried this to date.
What is so odd is that I was very to close to just abandoning media.net when google decided to lay an egg and give me very low CPC ads. My 30 day experiment had only two days left and I was ready to declare a winner.
So, I'm back to having little confidence that adsense has any long term viability for me. So I just mixed the adsense and media.net on the same pages. I'm giving adsense the crappy spots since they gave me crappy paying ads. Both will end up getting more traffic, just less adunits. Media.net should be happy with that since they've been asking me to give them more traffic. I'm still sticking to a single city however. Not yet ready to unleash this site wide.
All of that said, however, media.net has some bad days in terms of revenue, but averaged out has been higher than what adsense has given me the last couple of days. So they've won a repreive at this point, thanks to google.
If this topic is of interest to anyone I'll post what I find. Just let me know.
