;). In all seriousness, I would like to see the AI plan ahead for at least
technology and target selection and caravans for trade.

I've changed my position. I like this aspect of your idea. Have you considered
though:

What happens if on turn 356 the enemy moves 1/2 of his stealth bombers out to 
another city. If we still keep the old tile, the AI is now fooled into thinking
the enemy has incresed his force by half. You have to be very clever about
removing old tiles. You have to keep track of what unit type, moved last, and
if that same unit-type has moved again, discard/update affected tiles.
