Thank you Yoav. My personal responses below.

Also, I would like a comment from someone in the know: ChaCha (or at 
least its cousin Salsa) has had extensive cryptographic review, 
including an open competition. I am not sure the same is true for 
Poly1305, can someone enlighten me?

Best,
	Yaron

Yes, it's time we had good alternative crypto.

No, I don't see such a rush to implement. But feel free to prove me wrong.

Yes, we need alternative crypto for IKE just as we do for ESP.
