It was fairly painless. My wife (USC) came with me this morning and she had no problems getting in. They must have removed the restrictions they had on USCs coming into the embassy with their spouses.
Had one small problem. They wouldn't accept my wife's affidavit of support. She's going to be a grad student and she'll get a stipend that's more than the 125% of the poverty level. However, it won't start for another three weeks and they said that future income couldn't be included. Seems stupid to me. It's only 3 weeks. Must be a pain for others because I'm sure there's lots of people relying on job offers to cover this requirement. Fortunately her mother had filled out an I-864 as a back up and they were happy with that.
All in all an easy morning, took about 2.5 hours from first arriving at the gate to leaving the embassy (getting through security took about 40 minutes of that time). And I didn't need any of the extra information I had brought, like proof of wife's domicile & proof of relationship.
Best of luck to all those still waiting for the interview. If it's as easy as my experience then you have nothing to worry about.
