Amazon AWS's Elastic Beanstalk service is perfectly suited to this sort of problem. If you do your homework and design your system properly, it can automatically scale from a single box up to a giant group of servers capable of handling as many users as you can muster. It's pretty magical. We use it for everything we build, just in case.

Everytime I read anything about Vista's new features, I hear myself saying "fucking finally" like half a dozen times. Symlinks? Cancelling I/O? These are things other, better operating systems have had for over a decade. Anyone wanna start a pool for when they'll roll out a patent for symlinks?

Huh... I remember thinking the same thing about OS X when it first came out... Dynamic Memory Management? Finally! It only took you guys 20 years to catch up with the rest of the operating systems out there!
