As always, we can conjecture ourselves to infinity - and probably will.
But Cyan has stated that they were already very close to having their server model for MORE established prior to putting things on hold, and the news announcement seems to indicate that they already have in mind a preestablished model of how servers will be structured.
So, one request: until Cyan comes out with their official announcements and policies regarding this next incarnation, please phrase your comments in terms of your preferences, rather than stating "what we're gonna do is _____"
That said, here are my preferences:
1. There should once again be an authorization server. Without it, won't we once again run into the same problem we had during UU where players with modified datasets caused vault problems? (obviously, the terminology will have to be modified for the distributed server model Cyan has proposed, but I believe the concepts remain)
2. Cyan once again runs the authorization server. Why? Without authorization, how can rogue players be moderated or outright banned from the game? And would any of us trust any one server operator, any guild, or even a coalition of guilds to have that power over the whole system? As much as we may resent Cyan's judgment on occasion, I'm afraid they are the only authority that most of us would trust. While I'm not suggesting that Cyan resurrect internal ResEngs - far more than they can be expected to provide these days - I'm sure that even playing cavern cop at the auth server is not a role Cyan wants or can afford to host, so:
3. Cyan should be compensated for both its technical involvement and some level of personnel allocation in this project. We need their support in
so many ways throughout this project (just wait!), and at this crucial time they need our support. Their phenomenal generosity and goodwill deserves a bit of monetary return from each and every one of us that will be benefiting from it, even though this termed an open-source project.
I could also conjecture 'til the chaos come home, but I'll stop

here

for now....
