Hi Ted,
    I am not one of the authors of this draft, thus my final goal is not to 
publish an RFC with my name. As Service Provider I come to IETF to find 
standard and interoperable solutions that would fit my deployment scenarios.

I fully respect technical advices provided by technical people like you, my 
point is that IETF community should work with Service Providers to find 
solutions that both fulfill our requirements and they don't break existing 
stuff. In the specific case being able to provide load-balancing and redundancy 
in DS-Lite scenario is a requirement for us, thus I would like to see a 
solution for this coming from IETF.

Best regards,
Roberta

Mohamed, Roberta, you seem to have a very strong opinion that is based on the 
principle "someone insists that we have this."   I have to ask: what is your 
goal here?   Is your goal to publish an RFC with your name on it that does what 
you want, even though probably no-one will implement it because it requires 
code changes to both the server and client?   Or is it to get something that 
works, and can be used?

If it's the former, then by all means, ignore our advice.   If it's the latter, 
you might want to consider listening to the advice you're getting.   The point 
of the advice is not to be authoritarian or arbitrary.   It's to encourage you 
to write a spec that will be implemented and widely deployed, because it will 
require no code changes on DHCP servers or clients.

David's suggestion to use suboptions wasn't necessary.   You can use both FQDN 
and IP address, and just require that the client request both.   The problem 
with this is that you gain nothing over just doing FQDN in this case, since the 
client must implement a resolver in case the server doesn't send the IP address 
option.

I think you are driving very hard for a Pyrrhic victory.
