[dns-operations] PowerDNS has not Cookie feature?

PowerDNS have an IXFR converter (ixfrdist), similar to using the 
"ixfr-from-differences yes;" in bind, but they told us it is not really 
production ready right now, so we use bind to convert AXFR (from 
PowerDNS) to IXFR, which we need to supply minor zone data updates 
rapidly to outside DNS anycast providers.

We only use PowerDNS as a hidden Master, so I've not tried it as an IXFR 
client - all our slaves & resolvers are bind.

To be fair, its DNSSEC support is really easy to use and we make a lot 
of use of its REST/API.

The only issue I have with its DNSSEC support is that it signs on the 
fly, which means (if you used it to publish your zone) you would need to 
have your private keys on public facing servers - I'm not particularly 
comfortable with this, which is another reason I like having bind 
between PowerDNS and the outside world.

I've also recent hit a pretty severe performance issue with a catalog 
zone that doesn't affect bind. A single "dig" takes about 15 to 17 
seconds to return about 2000 records, where as bind returns them 
instantaneously.
