Cullen,
I'm sure there are some deployments where polling would be fine but there
are lots that don't find this acceptable.
The Internet alaredy has quite a bit of experience with renewal of parameters,
via DHCP and the DNS.
What is the justification that mandates a more complex model than
these use? It's not usually considered sufficient to simply cite the fact that
some operators somewhere want something different. There needs to be a
compelling case made.
It is always possible to invent edge cases that appear to justify a different
paradigm. The real question is about real need.
Given that operators have survived nicely with the DHCP and DNS models, what is
the /compelling/ need for doing something differently for the current proposal?
It will greatly help discussion to have operators represent themselves. If they
really believe the more complex update model is essential, they should lobby for
it themselves. The IETF is nicely open to such participation...
