The Kotel, (@thekotel) a Twitter service is allowing Jews around the world to post their prayers to the Western Wall in Jerusalem...via Twitter.
They explain on their website the service they offer includes a delivery of your tweet-prayer directly to the wall.
"All you need to do is to tweet your prayers and wishes, and they’ll be printed on real paper, cut down to small notes, and placed in the Wall."
Substantially cheaper than booking a flight and taking your prayer all the way to Israel. But hopefully they won't start offering virtual barmitzvahs at the Western wall via twitter too.
