On the Feasibility of Single-Server MMOs
GameSetWatch takes a look at the issues involved in creating an MMO that does not split its users among many different servers. They suggest that running a single "shard" is the next step in the evolution of MMOs, since it better allows player choices to have a meaningful impact on the game world; supporting different outcomes across multiple shards is a technical nightmare. They estimate, from the hip, that the cost to develop the technology required to support a massive amount of players (i.e. far more than EVE Online) on a single server to be roughly $100 million. Another recommendation is the strong reliance on procedural and user-generated content creation to fill a necessarily enormous game world.
TFA misses out one very important point.
Lag.
Lag is the primary concern amongst many EVE Online players. Certain areas of MMOs are more popular than others. Major Cities, battlegrounds, etc are places where large numbers of players congregate. Until we find a way to elminate the lag caused by sheer population density, single server MMOs are going to be strangled in what they can offer in terms of 'multiplayer'.
Think of how much fun it would be to crash one of those Eve Online ships into the shire!

"since it better allows player choices to have a meaningful impact on the game world"
Am I the only one here who doesn't want the collective impulses of 1 million 15 year olds impacting my game experience? Instead of theorizing about how awesome it would be to have a server with 5 million people on it at the same time, why don't they try to design a game that would actually be fun to play with 5 million other people on your server. I can't think of any, but if they can, I'd at least be willing to listen to their ideas.
Since the authors of this worthless article don't have any new ideas other than "WoW with tons of people on the same server!!!", I don't know how this thing got out of the firehose.
how long until we see a MMO that is run _entirely_ server-side - that is, a game that does all graphics and game logic calculations server-side, OnLive style, and simply streams HD-video to each client. If this considerable hurdle could be jumped, we might be able to see a lot more in the way of a dynamic MMO world, with actual physics, terrain deformation, collision detection, and a bunch of other features that are tough to do with the current client-server system.
Just.... no. There are many reasons graphics are done client side. Let me know when you figure them all out. Sure, something like this is theoretically possible, but only if you want to pay upwards of $200 per month to play that game. Since it's a lot cheaper for me to buy a really nice graphics card, why not render client side?
Actually, I see another even bigger problem, at least for more traditional (WoW-type) MMOs. How big should your world be?
Too little player density => people start complaining that it's pretty much a single-player game like Oblivion, except you occasionally see another player. Many games ended merging up shards more for that sensation of empty space than because of costs. (It's equally easy to just merge the physical servers inside a shard, to support a lower population per shard, if you're only concerned about hardware costs.)
Too many players on too little surface => lag (think: landing in Ironforge, back when it had the only auction house for Alliance), routinely having 5 players camping the same mob, and generally it just starts feeling cramped. Again, you have players starting to complain.
Basically if you want to be single-shard, you have to essentially guess how much population you'll get. Maybe just within the right order of magnitude, but guess nevertheless. It's not that trivial. On one side of the guessed-wrong spectrum you have WoW which got launched with only a handful of servers and had massive queues, on the other end of the spectrum you have more than one game who thought they'll be teh WoW-killer and then had to merge 4 servers in 1.
Merging or splitting shards is an easier way to deal with that problem than having to physically add or remove new areas, to fit the population.
Additionally, world size influences other things, like travel times, exploration, etc. There is an ideal apparent size where people don't feel like they're being packed like sardines and running around a back yard, but don't go "fuck it, I'm not spending another hour just running back to the quest giver" all the time either. It's easier to fine tune that if it's its own problem, orthogonal to everything else, than when it also has to fit the population numbers.
Basically if EVE's game type was well suited for that kind of one-shard world, more power to them, but for other types of MMOs it might actually be a bad idea.

Actually, while I'll agree with your main idea that it's undesirable, I just have to wonder about the 15 year olds quip.
From my limited experience -- and fully aware that the plural of anecdotes isn't data, but I have to start somewhere -- the vast majority of children I ended up grouped with were actually nice people and played the game well. Conversely, most of the more annoying trolls I've known, were middle-aged men. I guess mid-life crisis goes "I can still gank newbies" instead of "I can still get a car with a wing, and teenage hookers" in some people.
The thing that got me to start thinking about it all -- and bear in mind, I'm not saying it's the worst, just that it was a shock at the time -- was discovering that a (now ex) boss, a respected middle-aged, mid-level manager, was talking l33t in an MMO. I get a tell that, really, makes me wish I had a Rosetta stone to decrypt that garbled nonsense, and wonder who the fuck is that retarded kid? Lo and behold, it's the boss. I _know_ he can type very fast, so he doesn't even have the excuse of not having the time to type the "y" and "o" in "you."
Another midle-aged guy I know gets his jollies ganking newbies. That's his idea of showing how great he is, apparently.
One was literally the most retarded player I've ever grouped with. He managed to reach level 70 (at that time, the max) while still believing stuff like that if he takes a step back when an enemy slashes at him, the enemy will miss. 'Cause that sword doesn't reach to his new position, see. Geesh. Or he still thought that it's a good idea as a hunter to run backwards when he gets aggro, 'cause, see, he manages to squeeze in another ranged shot now and then that way. And generally, I mean, not just as in "hadn't figured out the game yet", but as in, "had the most ridiculous ideas and insisted that that's how the game works." He actually was proud of his "footwork", lemme tell you.
After a wipe or two I actually wished we had a 15 year old in his place. At least those tend to be good at figuring out a game.
One was not just a complete CS-head, but actually proud of his spewing the most offensive sexist remarks at anyone who had a female name in the game. There was stuff he was telling me (and you know you can't stop them from talking about CS even if you tried) that made _me_ cringe, and I'm a guy. And he's standing them beaming proud of how witty he was.
Etc.
So, 15 year olds? I can deal with 15 year olds. It's the older retards that I fear a lot more.

Marketing hype? That EVE is a single universe, with a peak concurrent user count of >50k? How's that 'hype' - it's true. Yes, they do multiprocess by switching you onto different servers when you jump system (sometimes). They also multi-process by having a proxy tier, a solar system tier, and a database tier. But that's not 'sharding' either. ... would have been generally negative to implement on the Tranquility (original) cluster.
When most MMOs have too many users, they end up firing up a new copy of the code on a standalone server, and let there be another 'copy' of the universe, for someone else to be 'king' of.
The only place that's happened with EVE, is the China implementation, and that was solely because China has rules regarding MMOs that
