I haven't had a chance to read nfsv4-security yet. That is at
the top of my to-do list.

After that, I think I'd like to huddle with Rick to discuss
how NFSv3 should work. Once we have something, we can present
options or discuss it on the mailing list.

In short, I agree this is something that needs to be discussed
at some point, but I'm not confident I'll be ready by Oct 27.
I'd prefer to see some discussion on list about this before
we bring it to a WG meeting.

(Given the limited degree of interactivity available during a
virtual meeting, I'd say we should consider restricting the
agenda to slides plus a couple of executive WG decisions for
each chosen topic, at least until the virtual meeting
technology improves).

This might not be a popular opinion, but DDP/MPA over QUIC in
my opinion would be a more straightforward option than plumbing
a bespoke authentication protocol into RPC/RDMA. A transport
level approach could also help resolve the authentication issues
that came up last time we considered a pNFS/RDMA layout type.
