ICANN UASG EAI WG is pushing the deployment of EAI. John Levine has run an analysis of the EAI Readiness of the Internet’s mail servers.
His DRAFT report is at https://docs.google.com/document/d/18W-dAr1Nhe_gVlFKDQZqsqB4bf5N86wryEcALnyUPTc/edit#heading=h.dba7p1kazxqa
From this report, the current EAI deployment  is amazing.
