This is another reason that I really like a local copy of the root DNS zone.

That copy has historically been a secondary copy.  But I'm trying to 
learn more about BIND's newer "mirror" zone option, which I think DNSSEC 
validates the the transferred copy.

LocalRoot using TSIG keys seems related and is on my reading list.

I would like to get to a point where many DNS servers could safely have 
a local copy of the root DNS zone.

See the pertinent RFCs for what "safely" means in this case.
