As an African -American prospective I can HONESTLY say that the answer to the ORIGINAL topic of this thread is
NO FREAKIN WAY 
will NPC/IFC/NPHC orgs ever be 50/50. Why would we even want them to be?
My college experience includes originally attending a predominately white institution in the South. I honestly considered joining a GLO I even watched them the first year they had "rush." I thought it was hilarious. Everybody running around all painted and smiley face. I was like WTF! One of my friends asked if I would like to attend their Rush with her. I love this girl but I had to make a decision at that time and I decided to tell her NO.
Later I transfered to a HBCU in the South and found a whole different world. My accent and mannerisms were seen as unique. I was accepted and very popular. I know I am attractive but at my predominately white instititution girls who looked liked me where everywhere. At my HBCU I was unique. Don't get me wrong I am not insinuating I was popular because of my looks. I am also pretty nice most of the time, outgoing and talented. I made these points to say that my "comfort zone" was expanded outside of the Black Student Association on my predominately white campus where that was the only place I felt totally at ease. It is funny but my husband says when I talk to my "white" friends on the phone my "accent" gets heavier "hey girl" versus when I talk to him or my black friends I am like "wassup girl." I guess it is true.
The NPHC org I am interested in joining like all the other greek orgs has a very in-depth history. My point is that when I read this history I feel an emotional pride for the Black women who forged a way. I would not feel the same way for the members of a GLO. Some of whom may have been slave owners or true KKK members. I cannot imagine an ethnic person who may want to join a GLO being proud of their founders or predecessors. Not to say that some past NPHC members may have not been a part of some hate group. But history and current events point out that white greek systems were very intergrated with Hate members.
I understand that GLOs pledge for the college experience NPHC orgs pledge for LIFE. Ah ha maybe that is why the Rush experience is so different.
Me? I am in it for LIFE!!!
As for the point of intergration. I think it is GREAT that their are members who chose to cross those unmarked color lines and go where their hearts take them.
