I'm fairly sure that there were screenshots of binary or trinary systems on the site...

You'd have to increase the size of a map immensely, and adjust the number of enemies spawned.

Other ships are usually placed when you travel through warppoints and the next map is loaded, so if you were to travel between the system on your map without using the warppoints, you'd run out of enemies.
If you put the stars at a somewhat realistic distance from each other, you wouldn't have to worry I suppose.

It might be nice to just have the neighbouring stars placed on the map - WAYYY out there, and without planets around them - just so you can see the light...

Perhaps an occasional "paired" system... Two stars orbiting at a very large distance, and each with a small planetary system.
