Neutrinos?

Occasionally someone frets about how the radio and TV signals we've been broadcasting over the past century could be a signal to some alien species saying, "Fresh meat over here!"  But what if no one has been paying attention to our signals because all the advanced races have a more efficient way of sending signals over interstellar distances?  A way that involves, not the familiar wavelengths of the EM spectrum, but -- neutrinos?
