While doing some general research on women and Sharia law, I found this incredible interview with a law professor at the University of Wisconsin, Asifa Quraishi. She's an expert on Sharia, and also teaches classes on Constitutional Law. (You can read about her on the law school's website) The interview is great, and provides a really solid foundation to start more research, if you're interested.
If you prefer, you can download the MP3 here.
Also, the series this is from, Inside Islam, is very good. I've listened to a few episodes already, and I'm impressed by the variety of people they interview and the even-handedness of everything. It's produced by Wisconsin Public Radio as part of the "Here on Earth" show. The topics are pretty varied, and are broken into categories on the information page.
UPDATE: Our own Prof. Huhn weighed in on Sharia law in one of his recent blog posts, if you're interested.
