How about Amateur Radio? (Score 2, Interesting)

All countries have procedures for licensing Amateur Radio stations. You might even get a worldwide contest scheduled where HAM radio operators get points for contacting as many "Kid Stations" as possible in a 48-hour period. There would be plenty of HAMS worldwide who would volunteer to help in a project of this sort. Amateur Radio fosters communication and cooperation. If international morse code shorthand is used, it can transcend language barriers as well.
