It's not horribly difficult to do at a higher level once you have group 
membership event notification. For example, there's a similar system 
for Java, <http://www.javagroups.com>, whose fundamental process-group 
construct is the Channel. Channels don't catch up on messages delivered 
while offline either, but there's a higher-level "building block," 
DistributedHashtable or ReplicatedHashtable, that does, by relying on 
nodes that are up to be notified when a node (re)joins the group and to 
send the current state of the world to the new node.
