I'm parsing most of that, but not all.

"Negotiating" chaff for wheat is the issue - who to trust, or rather,
how to achieve a functional, --against GPAs/ government adversaries--
model/ improvement over Tor!

If we rely on layers below end-user control, we lose a major element
of security we're trying to achieve here.

We can begin with low bw links for wheat in the chaff text messages -
bittorrent floods at all times would kill backbones in a sense -
that's why unlimited plans ultimately shape.
