I may be willing to run a 24/7 server eventually.
To be honest, the issue is never a lack of servers.
All the fun multiplayer servers up 24/7 anyway, like falling platforms, boss battles, speedkarts, prison escape, etc...
The issue is just a lack of players online.
Either there really aren't many non-US players at all (which I doubt), or most non-US players don't bother playing in our daytime, because they anticipate there being no players because the Americans are asleep.
