Greg,

I notice something that is very interesting to me, and maybe I need to
do some additional work on my own, but I'm going to try to sleaze past
that by asking you.

Sometime when Nessie streaming project became eSTREAM, it seems all
candidates have abandoned the function of authentication (MAC, HMAC,
etc).

Apparently, the task of including that is either insanely difficult,
or all of you are dropping that in the interest of performance. Am I
missing something?

Your comments and anyone else (Mr. Goldstein of Salsa20 particularly)
would be off the hook.
