I fully understand that. We're using this, along with parsyncfp2 (which you should checkout) to move 1.5PB of data a month across a 40Gb link. Not saying that HPN-SSH is only useful in that context but different people certainly do have different needs.
If encryption was absolutely required, I might try it over s_client/s_server or two stunnels, one in client=yes mode.
I'm assuming that would have different limits than you outlined above, although I don't think they do multi core.
