Anything beyond basic host-only TOE adds massive complexity for very
little gain: interfacing netfilter and routing code with a black box we
_hope_ will act properly sounds like suicide.

All this is vague handwaving without supporting evidence. So far we get
stuff like Internet2 speed records _without_ TOE. And Linux currently
supports 10gige... and hosts are just going to keep getting faster and
faster.
