As a professional and expert I would love to hear your thoughts and opinions on the use of elliptic curve crypto with SSH.  There was a concern (unsure of the validity) that NSA/NIST had compromised the algorithm used and ECC was unfit for 'secure' communication. 

2048bit RSA has been deprecated since that declaration and while 4096bit is still viable, the smaller key-size of ed25519 is appealing.
