Adsense vs. Adsense for Domains

What constitutes "content" to differentiate between them?

I have a small portfolio of domains (about 100) and just learned about Adsense for Domains. The "contact" form seems a bit intimidating, as though whoever's reading this de facto application is going to say "ONLY 100 domains, and they're not PREMIUM domains? Rejected!"

Anyway, that page on their site also notes something to the effect of "If you have any content on your web site(s), we recommend that you try Google AdSense"

So I'm wondering, what does "ANY" mean in that phrase? I don't think they'll accept me in Adsense for Domains. That's no problem, but I don't want to risk losing my regular Adsense account by putting these domains up with minimal content. Obviously, I can put together fairly differentiated 1-page sites on these, with differnt titles, page headers and a feed or something like that. They're not technically "parked" in my estimation, but I'd say it's just semantics because they're all just placed on a single IP and would draw some content from a database.

But what are the ramifications? I know Google's terms of service, but I'm wondering about the real-world implications.

Any advice from someone who perhaps has been through this?
