The CAP theorem says that out of Consistency, Availability or Partition
Tolerance, you can only have two.

If you expect WAN outages frequently, perhaps you should look at gluster's
geo-replication.  This should mean your reads and writes to the "near" side
of the link will be fast without having to do tricks with mounting the brick
directly; the far side will get a copy which will be a little behind.

Or else gluster is not the right tool, and something like lsyncd might be
better for your application: http://code.google.com/p/lsyncd/
