For the claim that NSA/CSS can break RSA 1024, it should be mentioned that the highest public known break of an RSA key is to a RSA 768, and above that, cash prizes has been given up to $175 000, with $75 000 at the RSA 896 point.
So if someone think they can put together a FPG'a or graphic cards system for less than $175 000, and that the system then will break RSA 1024, you can earn some "easy" money.
Anyway, the real question about the actually security concerning key-size is, how secure is recorded traffic. If the only protection here is the AES-128, than that is the thing to be concerned about.
