Considering DH is often used along with AES, I'd assume many encrypted communication streams implementing these that have been captured will likely be broken when this becomes a reality. Anyone care to shed some light on this? As far as ECDH goes... (afaik) most ECC implementations are vulnerable to quantum computing attacks...are there any decent post-quantum key exchange algorithms / protocols?

EDIT: nevermind, i've now read through the thread more and have found answers. :)
