Not something I've used, and it's difficult to countenance anything called that, but what Globus (globus.org) has become seems to be quite popular for transferring large research datasets between academic sites which subscribe. For ssh, there's https://www.psc.edu/index.php/hpn-ssh https://www.psc.edu/index.php/hpn-ssh for improving wide-area transfer speeds, and something else, I think.
