We don't even need servers really. You can just snail mail us pictures of what we'd get from the box and we'll pay. Occasionally mail us a picture of a forum post with details on what event is happening so we'll know to act excited. It'll be easier this way since you wouldn't have to actually update the servers, just send out a mail.
What about the delay for EU players though whenever a new update comes out? US players would already have their mail before the boat even arrives at Normandy. Besides, what's stopping me from sending pictures to my own address to get stuff for free? This is so easy to abuse I've already mailed myself a Node field aura and once I print out this image of a Polar Twilight Wolf Coat I'm getting that too. Actually you know what I'll send myself a groundbreaker set, I'm actually a beta player now. They should just make Spiral Knights a LAN game that we can play at Grey Havens HQ. No lag, no server costs plus it gets rid of the casuals.
