[Box Backup] Box Backup Hive?

[Ben Summers]

It's possible, but certainly not a priority. However, it would be  
nice to have automatic sync between servers so you can back up to  
more than one without using rysnc between them (which works well but  
is a bit of a hack), and if you were going to do that, you might as  
well implement this distribution method.

As for the code, the necessary abstraction is already in place --  
stores are written through the RaidFile interface only. This could be  
modified to do RAID over multiple servers rather than multiple discs.
