If it takes up to an hour before all connected users are known to the 
network, so be it. If users are normally hidden from the network this may 
have a reason (isolated node, RF link etc..). In that case you would not 
want to receive talks anyway.

If the new protocol aims in reducing the number of talk like announces 
then probably the broadcast type of behaviour is in place. Still no 
guaranties that a talk will be delivered succssfully unless ALL nodes use 
the same new protocol...
