Er.. possibly. Depends on what we want to achieve here.

The new protocol has the possibility of finding that elusive talk 
recipient where there is incomplete routing info about how to get to them.

However, that then means that you can't be sure that the recipient 
actually either is connected somewhere or even exists.

The protocol does not get a complete picture of the network until about 
one hour has passed (it may be less, but not more). This means we have 
to make a choice: either allow a "broadcast" to find the recipient or 
only do a "directed" talk if the recipient is in the routing table.

Discuss.
