No. OLSR provides a transport of messages, that should be flooded in an efficient way. Many routing protocols do support such. I say: all grown up routing protocols do (link state, BGP is another example).

Maybe an API for message distribution could be the way forward. This is more efficient than multicast (like BMF).
mdns / p2pd are examples. pud is another.
Has the packetbb iplementation such an API, so messages from another daemon are merged with hello / tc messages in same IP packet?

BTW, we need to fix mpr flooding some day (in v2 is fine).
