I like this text.  I think it reflects current operational realities quite
nicely.

I agree. The only suggestion I have is that an informational referenece to
Craig Partridge's oringal document on the timeout issue might be helpful to
include after the first sentence.

Yes. Maybe also add to the second sentence a cross-reference to section
7.1 on spoofing?
