DFS between two clusters

I am trying to setup a DFS namespace between two fail-over clusters.  I have 2 nodes for Cluster-1 and 2 nodes for Cluster-2.  I would like to have a single namespace for files located on each fail-over cluster.  This is for Server 2012.  Is this possible?

Please don't recommend this link, as it's not what I'm looking for.
