I would say that there is. I think that the feeling of real magic would be unmistakable. You would KNOW that you had seen something different. There would be no comprimises. Everything would be as fair and above board as possible. As open and as visual. Even if they didn't realise this consciously, surely subconsciously they would see a difference between your real magic, and it's directness, and that of your average card or coin or miscellaneous object worker.
Whatever they want you could give them. No questions asked, no funny procedures. Which is why I like your burlap sack idea so much. Actually, thinking about that there must be someway of performing a watered-down version of that in reality...got me working that one out now

I think that setting would play an important role as well. Do a levitation as Kati described on a stage in The Magic Castle, and there's all sorts of room for possible methods. Do it out in the open - or in their house - and let them come up and check for themselves - and then you have something incredible. As well as that, a real magician would not stick to things identified with magicians. He or she would probably discard the old pieces and do things we can only dream of.
