Well, here is a good news: it does work in other systems, as long as you produce valid RSS code for the ads. I wanted to share my finds with you guys, so here is my YPN RSS for your own RSS feed system blog post that explains the format in detail. Happy coding!
I would have to say "no" because you don't get to change the RSS template at blogger.com (AFAIK), and you really should be able to in order to make this work. Blog software for your own site is free and plenty, why don't you just get one installed?
