Soliciting opinions on paper "A congruent phylogenomic signal places eukaryotes within the Archaea"

Been reading this paper which I posted about to Twitter recently: A congruent phylogenomic signal places eukaryotes within the Archaea.  It is very interesting.  Not sure what to make of it though.  So - in contrast to my normal ways of putting my ideas out there first and asking for / hoping for comment I thought - let's mix things up.  So - I am soliciting comments from people BEFORE I write down my comments.  Any ideas / thoughts / comments would be welcome.
