If you wanted to encrypt/decrypt, the best choice would be the AES-NI processor extensions standard created in 2008. Unfortunately I believe this hasn't been merged in either openssl or libnss. Last I checked sheepdog doesn't AES encrypt data blocks. Unfortunately the big performance killer in network communication that is not consistent is the need to sign data blocks (hmac SHA2 is very expensive) and there are no processor extensions for any of that. ATM there is no encryption/signing at all, so best place to start would be to implement that feature.
