Getting married remotely

Well, this is a new one on me:

Montana is believed to be the only state that allows marriages by proxy without the missing partner being connected to the ceremony by telephone. Texas and Colorado have proxy marriage laws but both states require the missing party to say their vows by telephone.

This is from a story about an Army PFC in Iraq who married a woman in Montana, without actually being present. This gives a whole new meaning to the concept of man-in-the-middle attacks.
