Benjamin Reed commented on ZOOKEEPER-107:

sorry to jump in late here. rather than adding the inform, why don't we just 
send the PROPOSE and COMMIT to the Observer as normal, and just make the 
Observer not send ACKs? That way we change as little code as possible with 
minimum overhead. It also makes switching from Observer to Follower as easy as 
turning on the ACKs. I also think Observers should be able to issue proposals. 
One use case for observers are remote data centers that basically proxy clients 
that connect to ZooKeeper. This means an Observer is just a Follower that 
doesn't vote (ACK).
