Distributed, snapshotting, checksumming filesystems for FreeBSD

[Kamil Choudhury]

The dream: a file system spread out over a variable, 
ever increasing number of hosts, presenting a single 
unified file system to any client host mounting the 
file system. 

>From the client's point of view, it is possible to 
snapshot the directory view that is presented. The 
client also has confidence that data written to the 
file system will be returned exactly as it went in. 

Now that I think about it, what I seem to be looking
for is a network aware ZFS that uses hosts as vdevs. 

Is there such a thing out there?
