Candle ceremony including all of your guests...

I was looking for unique ways to include guests in your wedding ceremony. I came across a candle ceremony where everyone is holding a candle and and the first one is lit and the flame is passed on until it reaches the last person and the the bride and groom use that flame to light their ynity candle. I thought it was pretty neat, but was wondering if anyone has seen this done before and what your thoughts are on this ceremony. Thanks
