I am confused as to what you're asking here, James. Thoughts on the OO in general? Thoughts on the similarity or difference between EO and OO?
Anyway, from the OO side (or at least the Copts), you will also find a range of opinions regarding similarities or differences between them and the EO, but that doesn't really matter. No individual within the Church may use his personal opinion to challenge the decisions of our hierarchy. So while we may or may not feel a great deal of spiritual affinity, sympathy, and/or love for another, we are not in communion. Individual circumstances may lead to intercommunion on a very limited, clearly delineated basis (e.g., Ethiopians and Eritreans commune at the OCA and Bulgarian churches back home in N. California due to the lack of any OO church within reasonable driving distance; I have seen it myself), but that is not to be taken as evidence of intercommunion on any wider level than those rare individual instances.
When I asked my own priest here in Albuquerque regarding the reception of communion by EO in OO churches or OO in EO churches, he was decidedly negative. Both he and individual members of the laity even went so far as to remind me before I left for my recent vacation to California that I am not to receive communion in any EO church (as I have told them about OO receiving in EO churches back home). I thanked them for the reminder of course, but I found it a little funny. As a catechumen, I can't yet receive communion in the OO
Oh well. Que sera sera, I guess. Many things stand in the way of true intercommunion, but with God all things are possible, and if it be His will, it will resume...on His timetable. I will say as one individual (future) OO that, having been formerly a Roman Catholic, I personally see the dialogues between the OO and EO as those most likely of all inter-church dialogues to produce tangible, lasting progress. They are about substantial issues and both sides take their commitment to (their versions) of Orthodox doctrine very seriously. I can't say I see the same in other ecumenical dialogues, unfortunately. I suppose it takes a serious church to maintain a principled disagreement for 1500 years or so and counting, while others appear to scramble for unity for its own sake, neglecting that whole "be of one mind" thing that some guy wrote down in some book somewhere.
