You would need places dedicated to holding this info, similar to a torrent site.
OP could be on to something. A landing page that directs one to a list of peers that contain lists of peers. The list of peers could be held many places. It obviously needs a hierarchial build to be able to grow, but without being on some kind of onion routing there is no anonymity.
My biggest concerns:
- How do you convince thousands to host your content?
- How do you update your content?
- How do you lock your content down?
