But advanced civilizations might be detectable through bandwidth: if you
are a Jupiter brain who wants to send your latest discoveries about the
ecology of ecologies and how it interlinks with the visions of the
zorgnyyl on Germanicus IV to a friendly supercivilization nearby, you want
to send it through a very efficient channel and with good compression. So
you want to use as short wavelengths as possible, but are limited by the
interstellar medium, pair creation and the Planck wavelength. So what to
look for might be bursts of gamma ray noise...

(No, I do not think the gamma ray bursters are the papers of the ETs,
they seem to contain some reduncancies and patterns).
