No :-)

The slightly more longer answer is that I don't think ZFS is what you're 
looking for, I believe there are other projects better suited (although I don't 
recall the names off the top of my head).

For starters, ZFS only offers at best dual parity raid, so if more than two 
computers went offline at once you could have problems.  I guess there's 
potential to just use multiple mirrors or copies of data, but I've no idea what 
performance would be like for that.

Then there's the question of how you connect the computers up.  You could use 
iSCSI, but my experience is that ZFS freezes for a good while when a device is 
disconnected.  I'm also not aware of any way to automatically reconnect or 
manage devices.

Then you have to consider the network overhead from ZFS re-syncing data if a 
computer goes offline and a 'hot spare' computer replaces it.  ZFS I believe 
will just go flat out, potentially slowing your network.

You may be able to bodge ZFS into a solution for this, but I don't think it's 
even ready for that yet, and there are in all likelyhood far better 
alternatives.
