Okay, just to back it up a bit, and try to get some clarity in the debate.

As I understand it, we are all happy with:

    Server                                          Client
    ======================================================

1)  TCP Listen()

2*) Peer_Discovery (UDP) ------------Multicast----------->
      + Version

3)  <--------------------------------------- TCP Connect()

4)  <---------------------------------- Peer_Request (TCP)
                                                 + Version
                                       + optional extras 1

5)  Peer_Accept (TCP) ----------------------------------->
      + Status
      + Version
      + optional extras 2

*Step 2 may be replaced with a-priori configuration, mDNS, etc...

What we are arguing about is who should be the Client, and who should be the Server.

So, I am now calling for everyone's answer to the following question:

"Should the modem be the Client or the Server in the above diagram, and why?"

I have intentionally left 'optional extras' 1 and 2 undefined as they may be relevant in your answers.

I will give my answers in a separate email.

If anyone has a problem with the above diagram, now is your chance to shout!

Cheers,

Rick
