air snort on the hubble?

The most efficient communication on a network is with digital packets (like the net). That way the fastest route between any two points can be used regardless in changes of use. An advanced civilization would be using this and eavesdropping on their conversations would REALLY be worthwhile. So what does it take to do this? Just look for a repeating pattern that could be packet headers , right? I'm someone here with vast lnowledge of networking would be able to write up a code snippet to detect these. Or maybe just run air-snort?

I thought that's the basis of SETI

The problem with SETI is it assumes that alien races took our route for communications. But for all we know, they could have stumbled on subspace signals before am signals and use them instead.

Subspace signals???

I would hope that alien civilizations would have moved beyond baseband communications.

But, what if they did evolve communication technology similarly to us? In that case we could recieve their radio and TV (or whatever mediums they developed) broadcast signals from many years in the past. Their modern communications are probably a bit more private.

Unless such an advanced alien civilzation has developed FTL communication AND chooses to share it with us, there will be no meaningful conversation, probably a few thousand of watching eachothers' entertainment programming before we can communicate.

Actually, the hydrogen band is one of the simplest and most reliable ways to send interstellar radio messages, since it's a relatively 'quiet' part of the spectrum. Assuming you'd *like* someone with a radio telescope to hear you, that's what you should use.
