YItzchak Adlerstein and the RCA

In a recent piece by Yitzchak Adlerstein at Cross Currents, he makes the point that the RCA's new decision about not accepting women's ordination has officially made them almost like the Agudah. He states that the the Agudahness of the RCA is in how they came to the decision to deny women's ordination as opposed to the decision itself.  It seems the primary reason for not allowing ordination is again the issue of, it looks like Conservative Judaism.  This argument has been used in the past 10 years regarding the debate about women receiving Aliyot in synagogue (see Mendel Shapiro and the response by Rav Yehuda Henkin in the Edah Journal and the more recent rehashing of the debate by Rabbi Riskin in 2008).  Anyway, I think we are beginning to see the true break between RCA Centrist Orthodoxy and something which would be defined as "Modern Orthodoxy."  I am not sure what the ramifications of a decision like this would be.  Would women now have to choose whether to be ordained or just learned with some sort of certification?  Perhaps we really are just arguing about the semantics of calling a woman a rabbi as opposed to something like Yoetzet Halacha?
