A very useful piece of work. Particularly the material on emergency key 
rollover. It took me some time to write the scripts to take into account TTL, 
propagation delays, and various key compromise scenarios.  The approach your 
work takes gives the implementer a clear framework.  Wish I had your work 
before.

Subject: [DNSOP] draft-morris-dnsop-dnssec-key-timing-00

John Dickinson and Johan Ihren and I have just submitted 
http://www.ietf.org/internet-drafts/draft-morris-dnsop-dnssec-key-timing-00.txt

The draft gives a rigorous description of timing considerations in DNSSEC 
key rollovers.
