all well and good, provided that this encryption and authentication
are actually compatible with that specified by higher level protocols
and the authentication actually meets the needs of users.
(if your network interface needs to use and verify users' credentials,
as opposed to the host's credentials, it might be a stretch.)

at least for some storage applications, latency is not as important
as bandwidth. e.g. you can do backups over a high-latency medium
as long as your bandwidth is adequate (though recovery from write
errors gets a bit tricky).

I'm sure it will be used behind firewalls in some cases but it's
inappropriate to assume that it will always be used behind firewalls.
Firewalls don't help with the majority of security threats, and
it's less and less the case that network topologies reflect
trust domains.
