I spoke to Ira about it awhile ago. I think what we decided was that
while technically you can do a DR path, b/c you can load a cache from
anywhere in the cluster, you won't know if the DR path is legal or
correct at point A vs point B. In contrast, the node_guid input is
valid anywhere you are on the cluster.
I suppose we could just allow it and the user has to understand this
fact??
