Object storage

[List]

Timo,

We are contemplating building an S3 compatible cluster of storage 
servers using Pithos <https://github.com/exoscale/pithos> and Cassandra 
to get multi data center redundancy and availability. Would it be 
possible to have multiple Dovecot servers in disparate geographical 
locations all talking to the same object storage, assuming it's 
consistent between sites?  From what I remember about obox the dovecot 
servers all keep a copy of the index locally and merge it with a file in 
the object storage at intervals, is this an issue with our concept?  
Also does your team have any performance analysis data on the obox 
plugin, or data on it's use in production?
