You're not making sense there. If there is no daemon, then you're
peer-to-peer, because there's no central component. If you consider
the kernel the central component, then peer-to-peer is almost
impossible by definition.

It seems that almost everybody here thinks that the plumbing (e.g.
transmitting messages in-order with multicasting) should be separated
from the policy (who communicates with who), possibly leveraging the
packet filtering infrastructure to implement the decided policy. What
it is you reject about that point of view, which seems relatively
normal when you think about building a collection of useful tools?
