Clemson's had the ClemsonLIFE program for a while now, and I think the first women enrolled in it joined sororities either spring of my senior year or the fall after I'd graduated so I didn't have first hand experience with their inclusion into the Greek system.
Here's an article that explains how it works for people who aren't as familiar with the concept. On the fraternity side, when Pi Kapp was rechartering at Clemson while I was there they gave bids to two men in the ClemsonLIFE program whose dads are also Pi Kapp alums.
Their story is special to me because I had some friends in the chapter and when I asked one of them about how David and Jacob were treated in the chapter he said "They're just my brothers. We don't see them any differently."
On the logistics side, I found an article describing Clemson's Sigma Kappa chapter giving bids to women in the program that says they attend Sisterhood round (round 3) and Pref only. I remember that when my chapter gave a bid to a woman in ClemsonLIFE Panhellenic had a separate, smaller bid day before the main bid day celebration just for the program participants and some women from their chapters, probably because the big celebration is really loud and overwhelming.
