Given the troubles that Anglicans and Roman Catholics are having with their American branches, I imagine the Patriarchs would rather keep a tight lid on their Orthodox jurisdictions in America.
My parish is part of a small diocese under the EP, and I've been able to steer clear of jurisdictional politics -- and I like it that way. I would like to see a unified Orthodox witness in America, but I understand there are all kinds of hurdles -- political, ethnic, cultural -- that have to be overcome before that can happen.
Actually, the problem is mostly with the Ecumenical Patriarchate.
Antioch has already given major independence to the churches under Metropolitan Philip and the Orthodox Church in America (of which I'm a member) has been autocephalous since 1970.
