I'm aware that 'tatooine' worlds don't make good habits for planets, normally. From what I've read, either a planet has to orbit one star really closely, or orbit both stars from a really long distance away.
I envisioned a kind of double solar system, where there are two stars that are close enough to orbit one another, but far enough away where they can each have planets of their own.
In such a situation, its possible to have habitable worlds orbiting both stars, but they would be conceivably close enough where intelligent life from these worlds could potentially have some awareness of each other, and possible communication, even with our own current level of technology.
Of course, orbital calculations are beyond me, and from my understanding would require a supercomputer to work out. I don't believe I've ever heard of an actual 'double solar-system' like this, which would lead me to believe that such a thing is not possible.
If it matters, I wasn't thinking of either of these stars as having that many planets. The stars are close enough where outer-planets like in our system simply can't exist. And one only has one planet: a gas giant, with multiple habitable moons. The other is more like our solar system (well, inner solar system anyway, there's only 3 or 4 planets).
