What to do about hitting?

I've been so frustrated lately with my son's hitting.  I know in my head all the right things to do to deal with hitting. I'm an advocate of positive discipline, I'm on a positive discipline e-mail list, I've even offered encouragement to others..yadda yadda yadda.  

What I was *not* prepared for was the intense anger I've been feeling inside when he gets out of control!  He hits visitors, his siblings, my husband and me.  When I calmly tell him "people are not for hitting" he pulls away, sticks his tongue out or screams no! Or just makes a face and runs away!  He has never been spanked! I have yelled a bit lately as my frustration has been rising, but I've really been working in that area.  ARGH!!!

I'm concerned with my anger when I feel he's not responding to my attempts to deal gently with this hitting.
I try not to act on it towards him, but its there coloring my ability to respond.  I'm also concerned with the hitting. DH and I have been arguing a bit lately, and I'm sure that has affected him.  I feel like his behavior is out of control, and I don't know what to do about it. We've always joked saying he's a "full tilt boogie", high energy type of child, but this is driving me crazy.
