Here is a statement of purpose from the webpage of the North American Assembly: "The purpose of the Assembly of Bishops of North and Central America is to preserve and contribute to the unity of the Orthodox Church by helping to further her spiritual, theological, ecclesiological, canonical, educational, missionary and philanthropic aims. To accomplish this, the Assembly has as its goals: i) the promotion and accomplishment of Church unity in North and Central America; ii) the strengthening of the common pastoral ministry to all the Orthodox faithful of this region; and iii) a common witness by the Church to all those outside her. In addition, the Assembly has as an express goal iv) the organization of the Church in North and Central America in accordance with the ecclesiological and the canonical tradition of the Orthodox Church." http://assemblyofbishops.org/about/assembly
It seems to me that the paths outlined in points i, ii and iii are designed to lead up to point iv. In theory, at least, the process is consistent with what both Isa and AWR have posited. The committees established by the Assembly are extensive and comprised of Bishops, clergy and laity and cover most imaginable subjects including Canonical Affairs, Canonical Regional Planning, Clergy Matters, Financial Affairs, Legal Affairs, Liturgy, Pastoral Practice, Theological Education and Youth.
Summaries of the committee structure, including membership and actions to date are available at http://assemblyofbishops.org/committees/
I think that much has been accomplished to date and that the framework to a solution is slowly but steadily being put into place.
