[Spread-users] Different message type, different service?

[Jonathan Stanton]

There is a third function discard_packet which also delivers SAFE.

Unreliable are treated as reliable in this implementation of Spread.
Causal are treated as Agreed in this version.

So in essence, unrel, rel are delivered by deliver_reliable; causal and
agreed are delivered by deliver_agreed, and safe are delivered by
discard_packet. 

This is a simplification, but shows the rough mapping.
