With this kind of attitude and response it's hard to say what can be accomplished at this point.
From the article;
"We voluntarily chose to do it which means it could last for one day or one year, it depends on us," Mr Rohani was quoted as saying by Reuters news agency. "As long as Iran thinks that this suspension is beneficial for us it will continue and whenever we don't want it we will end it." Mr Rohani added that he did not expect they would sign the additional protocol before 31 October but "probably before 20 November".

Iran is showing goodwill to relax IAEA pressure (probably by the request of the Russian's) and to stall so work can continue. If we really want to know how far along Iran is all you have to do is ask the Russian scientist who helped Iran with the reactor. But then again Russia is finding out that Iran has not been telling them everything about there nuclear intentions and now Russia is a little worried. You would think they would have learned by now but maybe visions of rubles flowing there way blinded them.

I wish the EU success, but I think Iran is doing what North Korea did to Clinton, say one do another. It will probably come down to Israel or the US sending a squadron to take out the reactor.
