I've got some questions about
 - How did the Coda client choose the server to speak with,
   and is there a sort of load balancing mechanism, or the (or
   every) client is/are always talking the same server, as soon
   is always reachable ?

 - I'm not to have well understand the way Coda share data.
   Within a cell, every server share the same data. So there
   is no way to extend the total amount of data available
   by adding a new server ? The only way is to add a disk
   or a partition in each server of the cell ?

Thanks a lot.
