In fact, I've experimented with both scenarios (a payload-less) event
type scenario (that's what we're doing with Radio right now), and a
publish scenario with Peerkat, where the whole item is published.

I don't think either of these two scenarios are in question in either
case; I think it's more related to what mechanism is looking after any
data that might be polled (in the Radio case, for example, it's a
nation of an RCS (Radio Community Server), and the Radio desktop itself.
