What's your particular situation? Do you have extremely complex transparent objects that need to be rendered perfectly, or do you just need a solution that's on par with current-gen games?
I previously encountered a problem of transparent dresses and hair rendering. I didn't figure out a perfect solution at that time.
You probably want k-buffers for that. Much like the OIT method of A-Buffers but limited and designed to handles hundreds of transparencies like you would encounter with hair. Here's a paper.
