My key concern is that we do pick something. The choice of AES, SHA1 and SHA256 all seem pretty easy. (I include the SHA1 and SHA256 because I assume they would be needed to verify a certificate chain even if the transport integrity did not use them). I see the latest draft has Elliptic Curve for asymmetric crypto. Given the direction of Zigbee, I'm fine with that.
