I would like to make a summary of yes and no and maybe's for the protocol that could be (after further enhancements) presented in SFO.

Here is a quick dispatcher side list of questions I try to address right now with "C" functions and real machines in mind. I read this list to try to get ideas/responses, so I have not yet formalized a list of questions to address, so it is only a few and in disorder. Different thninking it seems. If it may help?

  - is it (dispatcher) meant to be single? or to work in:
     - coordination (one is master)
     - cooperation (related egal)
     - distribution (lose equal / specialized )
     etc.

  - can it delegate the dispatching role?
     - on load
     - by default (failure)
     - on rules
     - how
     - what is the inter-dispatcher protocol
     - does it include axfr or each dispatcher is by its own?
     etc.

  - which servers does it relate with?
    - how the servers letit know they are there
    - how does it négotiate cooperation
    - how is that information memorized?
    - how is it maintained (refreshed)?
    - what are the recovery procedures
    - are there connection/task priorities supported?
    - is competing support supported?
    - are there some task recovery support?
    - type of channel/security support

- how is the user to remotely contol the ONES server
  - information it is to pass?
  - when?
  - TTL?
  - dissemination? When?
  - reporting to the user?
  - cancellation/zapping ability
  - negociations
    etc.

- how do we want to write the specifications of the protocol?
   - plain language
   - specialiized language
   - specific high level language adapted to the architecture
   - or work on the definitions as we progress
   - "C" examples as function or a reference default
      OPES dispatcher and servers.
