Search for Extraterrestrial Intelligence
Gravitational waves, like EM waves, can be used to transport intelligent signals. Alien civilizations may be advanced enough to have discovered how to generate (and/or modulate) gravitational waves. These waves could be detected using gravitational wave detector technology.
Gravitational waves would probably be the preferred method of extraterrestrial communication for the following reasons:
Since the Einstein@Home project is based on SETI@Home software, SETI scientists can also analyze the output of gravitational wave detectors for intelligent signals. A Time Variance detector would be the most suitable for SETI since it is designed to detect high frequency gravitational waves.
Detection of intelligent signals may be achieved by implementing the following:
I had the pleasure of presenting a poster at the AbSciCon 2008 conference at the Santa Clara Convention Center; Session 19 - Future SETI: Technologies, Techniques, and Strategies. The poster gives a more detailed view of my idea: Searching gravitational waves for intelligent messages.

"After billions of years of biological evolution - on their planet and ours - an alien civilization cannot be in technological lockstep with us. There have been humans for more than twenty thousand centuries, but we've had radio only for about one century. If alien civilization are behind us, they're likely to be too far behind us to have radio. And if they're ahead of us, they're likely to be far ahead of us."
