Wow, a lot of discussion on this topic, I think now is the time to give 
this thread a new start.
Let's inventorize improvements and issues, create JIRA's for them and then 
come up with solutions for them.

Maybe I've got it (completely/partially) wrong, but this is my attempt to 
summarize the thread.
A start, 1 to 4 are improvements IMHO, 5 to 7 are issues/JIRA's, should 
two be created for 6 and 7?

1) Bind views
Bind Views are nice to implement branches, and if you want to use branches 
then DNS views are almost mandatory.
We could even decide that they are mandatory, but I don't see what 
relation they have with DNS problems in the sense of resource 
utilization/load.
So the whole views discussion should be part of the whole branch design.
2) SipX issues a lot of queries
I think the load is not that high, but it's easy to make a linux box 
cache.
To create a self refreshing cache is nice, but it means reinventing the 
wheel. The wheel will allow a higher topspeed, 
but I think sticking to the tried and tested "wooden wheel" caching DNS is 
a tremendous step forward.
3) HA optimization
HA should be as fluent as possible.
Do we need to lower TTL's ( what does it bring, it would mean dynamic DNS 
SRV records)
or rely on DNS to give a list of servers for each service and let the 
clients/servers find an active box/service.
4) DNS server failover (on linux level)
This can be optimized for faster failover
5) SipX resolving unused services
SipX resolves tls records although tls is not used (already a JIRA: 
http://track.sipfoundry.org/browse/XX-9639)
6) SipX resolving records not listed in sipx-dns or/nor DNS advisor
_sip._udp.rr.first.internal.epo.org
is an example
7) A record for domain needs to be there
According to Tony, I have an A record that I need (for XMPP :) so can't 
confirm.

etc etc
