One thing that I don't understand though - why do A.I. nations far away from you declare war on you, do a few distance spells (funny how they seem to know exactly where to launch those spells to target your armies even though they're not supposed to know where they are), and then nothing?

The AI is just as capable of sending scouts around as a normal player, so I expect this is where much of their knowledge comes from.
