If the people making attack code would stay out of space (both
for dest and src) it would be a big improvement.
And if the people making attack code were forced to use real IP address, or, put another way, if you could guarantee that the source IP address on an attack packet was the actual source of the attack, it would help in tracking attacks.

Before you say "we know where bot-net attacks are originating, but cannot get them to stop", that is another problem. As Rob said, problems are solved in steps, not with one wave of the magic wand. And saying "step one won't solve the problem so we shouldn't even start" is not, IMHO, a good idea.
