We've just come back from a wedding in Phoenix, Arizona, which was Skyped via a laptop with Wireless Internet to a standard PC using Skype here in Ireland. Worked a treat - the laptop holder just held the screen open so the inbuilt camera could capture the action, and the person at the other end, who happened to be in bed about to give birth, was able to see everything as we were all able to see her on the screen of the laptop. You just need availability of Wifi at the location of the wedding, a fairly decent laptop, Skype at both ends and away you go. Your friends in Ireland who can't travel could all meet up and have a wedding party at this end. Enjoy and good luck!
