OK, can we make a distinction between limited intercommunion and full communion?
No, there has not been an agreement reached on full communion between all EO and OO Churches. Unfortunately, it probably won't happen in the near future either.
However, there have been local, limited intercommunion agreements between some EO and OO churches, spearheaded by the two Antiochian Jurisdictions. So let's not pretend that there is no intercommunion at all, as there clearly is.
