Hello Timo,
i am currently playing around with the new director service and i am 
really looking forward for it in 2.0
Wouldn't it be better to use a consistent hash function instead of the 
md5 ?
So that you would only get a new assignment of users belonging to the 
failed server and not a "complete remapping".
With this setup it might be possible to store local indexes in a NFS 
Backend setting, as the users stay kind of sticky to their server.
And there would also be no need for the distribution of the currently 
active mappings within the ring. Maybe only for the state for the servers.

Regards,
Oliver
